Original Pull Request: https://github.com/netbirdio/netbird/pull/3009

State: closed
Merged: Yes


Describe your changes

When I remove 80 http port in Caddyfile, netbird client cannot connect server:443. Logs show error below: {"level":"debug","ts":1733809631.4012625,"logger":"http.stdlib","msg":"http: TLS handshake error from redacted:41580: tls: client requested unsupported application protocols ([h2])"} I wonder here h2 protocol is absent.
