HTTP 502 Error When Testing Postgres Source The error you're seeing — "Airbyte is temporarily unavailable. Please try again. (HTTP 502)" — is a known platform infrastructure issue, not a problem with your Postgres connector configuration itself. Root Cause The most common cause is a mismatched 
WORKLOAD_API_BEARER_TOKEN
 between the Worker and Workload API Server pods. Workload API calls get rejected with a 
401 Unauthorized
, which surfaces as a 502 error in the UI. [HTTP 502 Issue] Fix / Workaround If you're running Airbyte via 
abctl
(self-hosted), follow these steps: 1. Find your container ID:
Copy code
docker ps
2. Enter the container:
Copy code
docker exec -it <containerID> bash
3. Inside the container, run the following:
Copy code
# Check current pod status
kubectl -n airbyte-abctl get pods

# Generate and apply matching auth tokens to both services
BEARER_TOKEN=$(openssl rand -hex 16)
echo "Generated token: $BEARER_TOKEN"

kubectl -n airbyte-abctl set env deployment/airbyte-abctl-worker \
  WORKLOAD_API_BEARER_TOKEN="$BEARER_TOKEN" \
  INTERNAL_API_AUTH_TOKEN="$BEARER_TOKEN"

kubectl -n airbyte-abctl set env deployment/airbyte-abctl-workload-api-server \
  WORKLOAD_API_BEARER_TOKEN="$BEARER_TOKEN"

# Restart both services
kubectl -n airbyte-abctl rollout restart deployment airbyte-abctl-worker
kubectl -n airbyte-abctl rollout restart deployment airbyte-abctl-workload-api-server

# Wait for rollouts to complete
kubectl -n airbyte-abctl rollout status deployment airbyte-abctl-worker
kubectl -n airbyte-abctl rollout status deployment airbyte-abctl-workload-api-server
[HTTP 502 Fix] [Related Issue] Alternative (Helm deployment) If you're on a Helm-based deployment, you can also set the token across all three deployments:
Copy code
TOKEN=$(openssl rand -hex 24)
kubectl -n airbyte-abctl set env deployment/airbyte-abctl-workload-api-server WORKLOAD_API_AUTH_HEADER=Authorization WORKLOAD_API_BEARER_TOKEN=$TOKEN
kubectl -n airbyte-abctl set env deployment/airbyte-abctl-worker WORKLOAD_API_AUTH_HEADER=Authorization WORKLOAD_API_BEARER_TOKEN=$TOKEN
kubectl -n airbyte-abctl set env deployment/airbyte-abctl-server WORKLOAD_API_AUTH_HEADER=Authorization WORKLOAD_API_BEARER_TOKEN=$TOKEN
kubectl -n airbyte-abctl rollout restart deploy/airbyte-abctl-workload-api-server airbyte-abctl-worker airbyte-abctl-server
[HTTP 502 Fix] Multiple users have confirmed this resolves the issue. After the rollout completes, try retesting your Postgres source again. 👍 0 button 👎 0 button ℹī¸ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
