CF tunnel container not communicating with other containers

I have just installed the CF tunnel docker image as documented. The tunnel is up and running with status “HEALTHY”. Inside the container logs I get the error:

Updated to new configuration config=“{"ingress":[{"hostname":"", "originRequest":{}, "service":""}, {"service":"http_status:404"}], "warp-routing":{"enabled":false}}” version=12

The container on is up and running and can access it from public IP if I open port 3000 on firewall. From that container I can ping the tunnel container so I really do not understand what the issue is.
