Hi everyone ^^

Really easy setup. Two websites, one caddy reverse proxy.

Site is reachable on 8080 via public domain just fine:
https://web-production-8574c.up.railway.app/

But trying to get any routing from the reverse proxy fails.

I ssh'd into the reverse proxy service, pinging the internal route works fine, calling a wget against the internal route and port does not - simply runs into a timeout / never returns (see screenshot).

I know there is only IPv6 routing for private networking (even though now there is an information, that IPv4 is also available?). But neither :: nor 0.0.0.0 worked when starting the app (Nitro based server / Tanstack start).

Any pointers? 🙏
