Error 1033 Cloudflare (piefed.social)

I don't know what to do, I'm experimenting with creating a Lemmy instance. it's listening on port 8536 but cloudflare won't respond and connect and while i connected the tunnel to the instance, i can't figure out the error or how to make it connect to the server.

"Failed to connect to localhost port 8536 after 0 ms: Couldn't connect to server"

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.

Cloudflared, yes. "curl: (7) Failed to connect to localhost port 8536 after 0 ms: Couldn't connect to server"

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.

Odd, thanks! akaris.space

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

To add: (I'm just going down the checklist here https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/)

  • Can you show us that cloudflared is actually running. I wanna see it
  • Does your firewall allow the connection
