<DOMAIN>/<PATH> point to tunnel and show local service

New here, i set clouflared up so points to a local homepage docker service and it works, however i cant make / to point to another local docker service.

..com points to 192.168.X.X:3015
..com/portainer points to 192.168.X.X:9443 (this is not working)

i meant:
subdomain .domain. com points to 192.168.X.X:3015
subdomain .domain. com/portainer points to 192.168.X.X:9443 (this is not working)

Can you share the errors that you are getting? Are you seeing like a 404 error, a 502 error?

One thing to keep in mind is that tunnels are not a reverse proxy for subdomain.domain.com/portainer should go to 192.168.X.X:9443/portainer.
