• SameSite and cookie policies: if your app relies on cookies (session or auth) alongside the token, Chrome’s SameSite rules can block cookies in cross-site contexts. Check cookie attributes (SameSite=None; Secure) if applicable.
• Third-party extensions / privacy settings: test in an incognito window (with extensions disabled) to rule out an extension or privacy setting that blocks requests.
• Network / firewall differences: confirm Chrome is not using a different proxy or extension that changes requests. Some enterprise setups treat Chrome differently.
• LiveKit server logs: check the LiveKit server logs for the validate request and any errors returned. If the server rejects the validate request, the client will abort.
Targeted diagnostic steps to run now
1. Open Chrome DevTools Network tab and reproduce the failure:
◦ Find the GET to /rtc/validate and check the response status, response body, and response headers (particularly CORS headers).
◦ Check Console for any additional errors (CORS, Mixed Content, blocked cookie, or WebRTC-related warnings).
1. Try Incognito mode (no extensions) and reproduce.
2. Reproduce on Chrome on a different machine or network to rule out local network/proxy.
3. Capture the exact response body of the /rtc/validate call and any server-side log lines for that request.
Questions to narrow this down
1. Which Chrome version are you using?
2. Are your app and LiveKit server served over HTTPS? Do you use a TURN server?
3. Is your LiveKit self-hosted server version known (server version number)?
4. Do you generate tokens server-side? Are tokens signed with HS256 (shared secret) or another method?
5. Can you paste (or share) the response status and headers for the /rtc/validate request from Chrome DevTools (redact tokens)?
6. Do you see any CORS or Mixed Content errors in the Chrome console?
What I can do next once you share answers/logs
• If the validate response is missing CORS headers, I’ll tell you exactly which headers to add.
• If Chrome rejects cookies (SameSite), I’ll show how to set cookie attributes to work in Chrome.
• If the token appears rejected, I’ll help you validate token generation and clock skew.
• If DevTools shows a specific error message, I’ll give targeted fixes based on that error.
If you want, start by pasting the /rtc/validate response headers and any console error messages (redact tokens). I’ll walk through the exact next changes to make.

Important production notes and recommendations
• Those files live only on the machine running the egress container. If you don’t mount a host volume, the recordings will be lost if the container is recreated or the host is rebuilt.
• For durability you should either:
◦ Mount a host directory into the container (map a host path to the container’s output path) so files persist across restarts, or
◦ Configure cloud storage (S3/GCS) as the egress output destination so recordings are uploaded off-host automatically.
Example options
• Persist to host disk:
◦ In your docker-compose for the egress service add a volume mapping, e.g.:
▪︎ ./egress_output:/output
◦ Then ensure your egress config or egress request writes files to /output/...
• Use cloud storage:
◦ Configure S3/GCS outputs in egress.yaml and include credentials; egress will upload recorded files to the bucket.
If you’d like, tell me:
• The FileOutputs path you’re using in your egress.yaml (or paste the relevant snippet), and
• Whether you want to keep files on the host or use S3/GCS;
I’ll give the exact docker-compose volume mapping and the egress.yaml snippet you need to persist recordings.

03/23/2026, 10:29 AMstartRecordRoom call will save the recording where you expect and how to make sure the file is persisted. I’ll confirm what your code does and give clear next steps to ensure recordings are stored safely.
What your code does
• You create a directory path on the host/worker: /data/recordings/{roomName} and a filename like YYYYmmdd_His.mp4.
• You pass that absolute path as the filepath for an EncodedFileOutput when calling startRoomCompositeEgress.
• If the egress worker writes files to that path, the recording will be written to /data/recordings/{roomName}/{filename} on the egress worker’s filesystem.
Important caveats and how to ensure persistence
• The egress container must be able to write to that path. If the path is inside the container filesystem and not mounted to the host, files will exist only inside the container and can be lost when the container is removed or recreated.
• To persist recordings across restarts, mount a host directory into the egress container and ensure the egress process writes to the mounted path.
Recommended changes (example)
1. Update docker-compose for your egress service to mount a host folder:
◦ Map a host path (e.g., ./egress_output) to the container path your egress process will write to (e.g., /data/recordings).
◦ Example volume line (in your egress service):
▪︎ - ./egress_output:/data/recordings
1. Keep your PHP filepath as /data/recordings/{roomName}/{filename} so egress writes directly into the mounted directory.
2. Ensure file permissions allow the egress process to create directories and write files (owner/group and permissions).
◦ If necessary, run the container with a user that matches host permissions or set mount permissions appropriately.
Optional: Use cloud storage for durability
• If you prefer not to manage local disk persistence, configure S3/GCS outputs in egress.yaml so egress uploads recordings to a bucket. That avoids manual host-mounting and protects against container/host failures.
Quick checklist to verify now
• Confirm your docker-compose includes a host->container volume mapping for /data/recordings.
• Start a recording, then inspect the host egress_output (or whatever host path you chose) for the MP4 file.
• If the file doesn’t appear, check container logs and file permissions for errors.
If you’d like, paste your egress service docker-compose snippet and your egress.yaml (or tell me the exact host path you want to use). I’ll provide the exact docker-compose volume lines and any permission commands you should run.

03/23/2026, 10:37 AM/data/recordings/{roomName}/{filename} as the EncodedFileOutput filepath. That tells the egress worker to write the MP4 to that path on the worker’s filesystem.
• Your egress.yaml snippet does not include any FileOutput (local path) or cloud storage configuration, so egress will write to the local disk of the egress worker container by default.
Why recordings might not appear on the host
• If the container has no host volume mounted at /data/recordings, the files will be created only inside the container’s writable layer and will be lost when the container is removed or recreated.
• Permissions: the egress process inside the container must have write permission for /data/recordings (or the mounted host directory).
• Path mismatch: the path your PHP code uses must match the path exposed inside the container (the container’s filesystem path).
What to do to persist recordings (recommended)
1. Add a host volume mapping to your egress docker-compose:
◦ Example (inside your egress service):
▪︎ volumes:
▪︎ ./egress_output:/data/recordings
◦ This maps a host folder ./egress_output to the container path /data/recordings that your PHP code writes to.
1. Ensure permissions allow writing:
◦ Set ownership or permissions on the host directory so the container user can create files. For example:
▪︎ mkdir -p ./egress_output
▪︎ sudo chown 1000:1000 ./egress_output # replace 1000 with the UID the container uses, or use a permissive mode temporarily
▪︎ chmod 775 ./egress_output
◦ Alternatively run the container with a user that matches host UID/GID.
1. Keep your PHP filepath as /data/recordings/{roomName}/{filename} so egress writes directly into the mounted directory.
2. Verify by starting a recording and checking the host folder ./egress_output/{roomName} for the created MP4.
Optional: configure file output in egress.yaml (not strictly required)
• You can also explicitly configure FileOutputs in egress requests or in egress.yaml if you want defaults. If you do, make sure the output path points to the mounted directory (e.g., /data/recordings/...).
Notes about your current egress.yaml
• The shown egress.yaml provides Redis and credentials but no output configuration. That’s fine because your PHP code supplies a filepath, but persistence requires the host mapping described above.
• Make sure your api_key / api_secret and ws_url are correct for your environment.
Quick checklist for you to run now
• Add the volume mapping to the egress service and create the host folder.
• Ensure directory ownership/permissions match the container user.
• Start a recording, then check the host folder for the MP4.
• If the file does not appear, check egress container logs for errors (permission denied, write errors).
If you want, paste your egress docker-compose service block and I’ll provide the exact lines to add and recommend permission commands tailored to that compose file.

03/31/2026, 10:26 AM/data from the host into the container (via - /data:/data), so your PHP code’s /data/recordings/... filepath should write to the host path /data/recordings/.... Since you still don’t see files, let’s walk through the most common causes and targeted checks to pinpoint the problem.
Quick summary of what should happen
• Egress writes the MP4 to /data/recordings/{room}/{file}.mp4 inside the container.
• Because you mounted - /data:/data, that path inside the container maps to /data on the host. Files written there should appear on the host at /data/recordings/....
What to check now (run these in order)
1) Confirm the file is being created or errors exist
• Check egress container logs:
◦ docker-compose logs -f egress
◦ Look for any errors mentioning permissions, failed writes, or invalid output path.
• If you have the egress_id from your PHP response, search logs for that ID to find related entries.
2) Verify the exact path used by egress
• Inside the running container, list the path:
◦ docker exec -it egress_container_name /bin/sh
◦ ls -la /data/recordings
• If the directory or file exists inside the container but not on host, the volume is not what you think.
3) Confirm the host mount is actually applied
• On the host, run:
◦ mount | grep " /data "
◦ or check docker inspect to see container mounts:
▪︎ docker inspect container_id --format '{{json .Mounts}}' | jq
• Ensure the container’s /data is bound to the host /data (not a different path).
4) Check host and container permissions
• On the host:
◦ ls -la /data
◦ ls -la /data/recordings (if it exists)
• Ensure the host directory is writable by the UID the container process runs as. The egress container may run as a specific uid/gid.
• If you’re unsure, try permissive test (temporary):
◦ sudo chmod -R 777 /data/recordings
◦ Then restart egress and try recording again.
• If that works, tighten permissions by setting appropriate uid/gid on the host to match container user.
5) Confirm your PHP filepath and egress worker are aligned
• Your PHP code passes /data/recordings/.... Make sure there are no typos and that the egress process actually receives that filepath in logs or the egressInfo response.
• Check egressInfo (or container logs) to ensure the egress worker accepted a file output and didn’t fall back to a different output type.
6) Verify there’s no SELinux/AppArmor interference (Linux hosts)
• On SELinux-enabled systems (RHEL/CentOS/Fedora), file creation may be blocked despite permissions.
• Quick test: setenforce 0 (temporary) and retry (don’t leave SELinux disabled in production). If that fixes it, adjust SELinux context for /data.
7) Check free disk space
• df -h /data
• If the disk is full, writes may silently fail.
Specific things to paste here (if you want me to diagnose faster)
• Output of: docker inspect egress_container_name --format '{{json .Mounts}}'
• Snapshot of the egress container logs around the time you start a recording (redact secrets).
• Output of ls -la /data on the host and ls -la /data/recordings inside the container (or state that the directory is missing).
• The exact egressInfo response if available (egress_id and status).
Suggested immediate test (quick sanity test)
1. Exec into container and create a test file:
◦ docker exec -it egress_container_name /bin/sh
◦ touch /data/recordings/test-file-from-container.txt
1. On the host, check if /data/recordings/test-file-from-container.txt exists.
◦ If it appears, the bind mount works and the issue is likely egress process permissions or the path the egress daemon is trying to write.
◦ If it does not appear, the mount is not configured as you expect.
If you run the tests above and paste the outputs (mounts, logs, ls), I’ll give the exact next steps (permission commands, docker-compose corrections, or SELinux steps) to get recordings writing to the host persistently.

03/31/2026, 11:37 AMdocker compose instead of docker-compose.
5) Check disk space and filesystem health (curl write errors can come from full disk)
• df -h
• sudo dmesg | tail -n 50 (look for filesystem or permission errors)
6) Ensure you executed init script with sudo (you did) OR run the script after fixing docker-compose
• After reinstalling docker-compose, re-run ./init_script.sh and watch for no errors.
Permissions and rootless note (summary)
• The script warned about rootless Docker vs privileged daemon. For production servers we normally run Docker daemon as a system service (privileged) and manage access via the docker group.
• Rootless mode is an option if you want the daemon to run per-user without full root privileges; it requires extra setup and has different filesystem behavior. For now, keep the default daemon mode and ensure docker-compose binary is correctly installed.
How this ties to your egress / /data mount problem
• A broken docker-compose or a failed init script can result in containers being started with incorrect mounts or not started at all.
• Once docker-compose is healthy and the egress container is running, the /data:/data bind should make container writes visible on the host—provided ownership/SELinux/permissions are correct.
If the docker-compose reinstall succeeds, then verify these egress checks (you may have done some already):
1. Start or restart your compose stack:
◦ sudo docker compose up -d egress
1. In the running container, try creating a test file:
◦ docker exec -it egress_container_name /bin/sh -c "mkdir -p /data/recordings && touch /data/recordings/testfile.txt && ls -la /data/recordings"
1. On the host, check that /data/recordings/testfile.txt exists:
◦ ls -la /data/recordings
If the file appears on host, the mount works; if not, share output of docker inspect for the container mounts.
What to paste back here (so I can give exact commands)
• Output of:
◦ docker --version
◦ docker compose version (or docker-compose --version)
◦ ls -l /usr/local/bin/docker-compose
◦ df -h
◦ sudo systemctl status docker
• If you re-run the manual docker-compose install attempt, paste any errors from curl or chmod.
• If you run the test file steps, paste results of docker exec ls and host ls.
If you want, I can give the exact docker-compose reinstall commands for your OS — tell me which Linux distribution and version you’re running (Ubuntu 20.04, Debian 11, CentOS 7, etc.). Once docker-compose is healthy we’ll confirm the /data bind and then proceed to verify egress logs and Chrome-specific issues.
