HI there,  
I have a webapp in a container that is evading traefik, as nother ever shows on [webapp.mydomain.com](http://webapp.mydomain.com).  
Somehow this container exposes port 80/tcp, regardless of the ports defined in the compose file.  
Configuration is virtually identical to other containers that have no issues.

Can the exposed port be a reason that traefik is struggling with ?  
What information can I offer for more details ?  
Cheers
