SAP Business One with Traefik as Reverse Proxy

Hi, I want to use Traefik as a Reverse Proxy for SAP Business One. but I currently fail with this error message:

Does anyone have an approach as to why it doesn't work that way? For NGINX it exists some Sample.conf's. But I dont want to use two reverse proxys.

I recommend to share your Traefik static and dynamic config, and docker-compose.yml if used.

There can be tens of reasons why it's not working: wrong IP, wrong domain, wrong port, wrong CORS, wrong headers, wrong routers, wrong services, wrong Host(), wrong Path(), wrong PathPrefix(). wrong provider, wrong network, wrong OpenID setup, wrong application settings.

Check Traefik debug log, check access log, check Traefik Dashboard, check browser developer tools network tab.

If you are looking for a working config, I think you have better chances at a more specific SAP forum.
