Has anyone successfully used Tailscale Serve on StartOS 0.4?
I’m testing the new Tailscale integration with Tailscale 1.98.9:1.
The node connects correctly, MagicDNS works, HTTPS certificates work and
https://startos..ts.net reaches Tailscale Serve, but Serve returns HTTP 502.
StartOS creates:
Tailscale Serve
→ http://localhost:20000
→ socat
→ 10.0.3.1:53632
→ StartOS UI
What’s strange is that from inside the Tailscale container both backend URLs work:
wget http://10.0.3.1:53632
→ HTTP 200
wget http://127.0.0.1:20000
→ HTTP 200
But accessing the same backend through Tailscale Serve returns 502.
Has anyone confirmed Tailscale Serve working on StartOS 0.4?
I’m wondering if this could be an interaction between the StartOS integration,
Tailscale 1.98.9 and userspace-networking mode rather than a normal Tailscale
configuration issue.
