Yeah, YunoHost explains why http://localhost:8536/ wouldn’t be working. If cloudflared and Lemmy are in separate containers you have to put an actual IP in, since localhost points to the container itself.

How are you accessing it without Cloudflare? How do you know that Lemmy is actually listening?

What’s the URL you using to access it without Cloudflare?

Edit: Also that curl tells me it’s not listening on that IP/port.

Can you access it without Cloudflare?

Does curl http://localhost:8536/ work?

You are using cloudflared right? Because normal (non-cloudflared) Cloudflare doesn’t support port 8536.

With dynamic DNS? Yeah it always has, as long as you can host a http server.

With a dynamic IP? It should do, the certs are only valid for 6 days for that reason.

You can host a page with an iframe, but you can’t directly change the DNS record to point to something that isn’t GitHub.
