This should be related to outline-go-tun2socks connection check. The server is reachable (using the old ss-local and tun2socks), but go-tun2sock reports that it is not. The error code is 4 UDPConnectivity, @bemasc can we ignore UDP connection issues during connectivity check?

[bemasc]

The client code doesn't ignore UDP connection issues during connectivity check, but it intercepts them and uses them to adjust the configuration automatically. If this is failing, it's because the subprocess return code is being lost.

It would help to insert a debug check (or expanded log statement) in the client JS to confirm the exit code that is being observed by checkConnectivity() in node.

Thanks @bemasc , I can take a deep look at the client logic.
