Summary

Hi, I am running shlink as a selfhosted instance with a postrgres db and the web-client, all of them inside their own docker and in the same network. All basic functions I tested so far have been working just fine. The only thing I did not get to work is the "Visited URL" column in the visit statistics. Every visit only lists http://127.0.0.1:8085/some-test-slug. The locations ont he other hand do work just fine, so he is ablet o determine the calling ip, but somehow uses the wrong host.

It only shows the docker host of the shlink service and hot the actual host it was called from. I also tried SERVER_NAME for the Host ReqHeader, but no luck either. It does feel like shlink does not use the Host Header at all, or the reverse proxy config is incorrect in some other way.
