Unable to connect to origin - Service is avavilble

I have setup a tunnel, working ok, I published a test service externally on my domain but all I get is

Unable to connect to origin. Please confirm that the tunnel is set up correctly and the origin is healthy.
Head to our [Developer Docs](https://developers.cloudflare.com/cloudflare-one/faq/tunnel/) for additional troubleshooting steps.

The local service can ping the name it’s available and a CURL request on the tunnel server returns the web page.

I can’t even find any logs.

Anyone have any ideas? I have tried opening a support case but they don’t respond (even though we are paying!)

I have sort of the same issue. Did you ever fix it?

Sorry, no, I couldn’t get any engagement from support so I gave up in the end!

Dang, yeah I’ve been looking through other posts and there is really only one guy doing most of the stuff
