  • This is not a support request

Is there an existing issue for this?

  • I have searched the existing issues

Current Behavior

Health check warning even when online and able to connect to coordination server. Causes degraded service over time.

# Health check:
#     - Unable to connect to the Tailscale coordination server to synchronize the state of your tailnet. Peer reachability might degrade over time.

Expected Behavior

Tailscale client should be able to connect to coordination server when online.

Steps To Reproduce

I posted the same issue in the tailscale github: https://github.com/tailscale/tailscale/issues/13906

Environment

- OS: MacOS Sonoma and Linux
- Headscale version: 0.23.0
- Tailscale version: 1.76.6

Runtime environment

  • Headscale is behind a (reverse) proxy
  • Headscale runs in a container

Anything else?

No response
