any tips for kubernetes on google cloud?
t
Thanks for reaching out, Richard. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Here are some friendly tips to help you run Kubernetes on Google Cloud, especially when deploying LiveKit: • Helm Chart Setup: Try using the official LiveKit Helm chart—it makes deploying Services, Deployments, and Ingress resources a breeze. • Networking Configuration: Make sure to set up host networking for your WebRTC traffic, configure GKE load balancers, and open the right ports (like TCP 7881 and UDP 50000–60000) so everything flows smoothly. • SSL/TLS Termination: Take advantage of GKE’s TLS termination support and double-check your DNS records. Don’t forget to keep your TLS certificates safe in Kubernetes Secrets for TURN services. • Resource Management: Give your pods enough CPU and memory to keep things running well, and consider enabling Horizontal Pod Autoscalers (HPA) to handle scaling automatically. • Security Setup: Keep your setup secure by using RBAC, network policies, and storing sensitive info securely in Kubernetes Secrets. • Monitoring: Set up Prometheus and Grafana to keep an eye on how things are performing. • High Availability: Deploy multiple replicas and use regional clusters to make sure your service stays up and running even if something unexpected happens. • Graceful Rollouts: Use termination grace periods (like 5 hours) to help your upgrades go smoothly without interrupting your users. If you want to dive deeper, check out example files like 
server-gke.yaml
and 
server-gke-vpc-native.yaml
for detailed configurations. Sources: Deploy to Kubernetes | LiveKit Docs | livekit-server/templates/service.yaml | Kubernetes & Helm Charts | livekit/livekit_composite | DeepWiki

livekit::rtc_engine - failed to connect: Signal(RegionError("error decoding response body: expected value at line 1 column 1")), retrying... (1/3) What might be the cause of this message?
t
It looks like the error message is pointing to a problem with the signaling connection to the LiveKit server. Don’t worry, here are a few things you can check and try to get things back on track: • Server URL and Credentials: Double-check that your URL and token are correct and nicely formatted. Make sure the URL is actually pointing to a LiveKit server. • Network Connectivity: Take a moment to check your network connection and see if any firewall settings might be blocking access to LiveKit. • Region Resolution: If you’re using LiveKit Cloud, make sure the region settings are set up properly and that the server supports region-based connections. • Retry Logic: Try increasing the number of retry attempts or tweaking the retry interval in the SDK. For instance, in the Rust SDK, you can adjust the 
join_retries
option inside 
EngineOptions
. If you’re still running into trouble, take a peek at the server logs for more clues, or just give me a shout—I’m here to help you sort out any specific setup questions!

can I disconnect a user from a room at cloud.livekit.io? If so, how?
t
Absolutely! You can disconnect a user from a room at 
<CLOUD_LIVEKIT_URL>
by using the 
RemoveParticipant
API. This will immediately and forcefully disconnect the participant from the room. Here’s a simple way to do it: 1. Use the 
RemoveParticipant
method from the server SDK, and provide the room name along with the user’s identity. 2. That’s it! The user will be disconnected right away. For example, if you’re working with Node.js:
Copy code
// Using Node.js
const roomService = new RoomServiceClient(LIVEKIT_URL, API_KEY, API_SECRET);
await roomService.removeParticipant(roomName, identity);
Just a quick heads-up: this action doesn’t invalidate the user’s token, so they could reconnect unless you use short-lived tokens. If you want, I’m here to help with that or anything else you need! Sources: Managing participants | LiveKit Docs | lib/src/core/room.dart

but can I remove them from the room using the cloud.livekit.io website?
