I am configuring Traefik to work as a reverse proxy in my development environment. I currently have applications running on different ports, and different PATHs.
My Environment:
Traefik is running on a Host (192.168.0.10). Listening on port 80, 443 and 8080 (traefik dashboard).
My applications are running on a different host (192.168.0.11).
Web application: 192.168.0.11:8200/web1 Backend: 192.168.0.11:8210/api1 Other web application: 192.168.0.11:8300/web2 Other Backend: 192.168.0.11:8310/api2
I want to redirect all these applications through a same subdomain (dev.domain.com) with Traefik + LetsEncrypt (acme).
For example:
When I access dev.domain.com/web1, I want to redirect all access to 192.168.0.11:8200/web1
When I access dev.domain.com/api1, I want to redirect all access to 192.168.0.11:8210/api1
And so on..
Below is the settings I'm using, Traefik version, etc.

Traefik works fine when I need to redirect requests to applications that are running on the host itself through Docker (via Labels). My helloworld.domain.com application works!
Traefik works fine when I redirect only one application. From the moment I configure the second application in the same subdomain, traefik gets lost in redirects through the PATH.
I searched the internet for use cases like mine, but I did not find people using Traefik to redirect the application outside of the Docker Engine, Kubernetes, etc.
