Hi folks

Installed the image, running ok on [LAN IP]:3001. Continued to create a Cloudflare tunnel and all good, with the tunnel up.

Using Entry Page set to Dashboard the [subdomain].[domain].[tld] brings up an error "Cannot connect to the socket server. [Error: websocket error] Reconnecting..."

If I change Entry Page to "Status Page" then the status page loads fine.

Any ideas?

Not sure whether it is related, but worth to try.

[freitasm]

Thanks, but likely not related. I already had this enabled for a year now as I use https://www.myrtille.io/ and it relies on sockets.

Cloudflare Tunnel does not support WebSocket :/
But maybe you can try this: https://community.cloudflare.com/t/tunnel-with-websockets/318111

[freitasm]

Thanks. That's interesting, seeing cloudflared/tunnel is explicitly supported and recommended in the documentation.

I will check post and work on the configuration.

Cheers

As I am currently using Cloudflare tunnel, I can confirm it is working with WebSocket.

[freitasm]

Interesting. I can see the requests coming through Cloudflare firewall and being allowed. so there must be something else.

[AlisaAkiron]

OK, I have got it to work.
It seems like my WAF rules (Managed Challenge to any HTTP/1.x requests) have sent a Managed Challenge to the WebSocket request which it could not complete.

Just set up a WAF rule to let this request pass and you're ready to go.

[freitasm]

Still doesn't work for me. I have created a rule at the very top. It allows traffic through but still getting the error:

May need to check the response with Chrome DevTools
