It seems the tunnel is failing to provide SSL correctly

For my subdomain “mempool” the tunnel is working fine. But for my subdomains “nostr” and “dl” the tunnel is failing to provide SSL correctly it seems. The config is the same, and the server is also the same. Only the port changes.

my domain is s-w.art. The tunnel is failing to provide SSL correctly it seems. That is strange because all 3 domains run on the same same VM only with a port change. Are the tunnels only supporting certain port ranges, or am i missing something here.

https://mempool.s-w.art/ (works) TLS noVerify on

https://nostr.s-w.art/ (not working) TLS noVerify on/off Tried both
https://dl.s-w.art/ (not working) TLS noVerify on/off Tried both

Tunnel / Public Hostname Services can use any port. The Tunnel (cloudflared) runs on your own servers, there’s no issue with it on that end.
However, for dl, it itself is redirecting to insecure http on port 2000

Cloudflare does not support port 2000 as an Edge Port (Network ports · Cloudflare Fundamentals docs), so that’s just going to time out. Even if it did, because it’s trying to force http, you’d just get an endless loop.

I’m not sure what type of app it is, but you’ll likely need to configure it to work behind proxy. This is an application configuration issue.

sostr gives me an Origin DNS Error, can’t test that one. Guessing you removed the public hostname?
