Serving from multiple Hostnames does not work anymore

### What happened? We used to serve multiple grafana instances from a single hostname grafana.loadbalancer.lan/fancy/pancy/subpath and it worked great with older versions. Furthermore we accessed the nodes directly via grafana1.direct.lan/fancy/pancy/subpath and grafana2.direct.lan/fancy/pancy/subpath The direct hostnames can only be accessed from within an administrative net. Via the Loadbalancer we can't control which grafana we access. Now we can't do this anymore. #works as expected: serve_from_sub_path = true #what should we set here? we can't set it empty, as then the default "localhost" is used domain = #this seems not to change anything at all and seems to be the problem enforce_domain = false #this will make any request be redirected to the domain set in "domain", no matter if enforce_domain = true or false root_url = %(protocol)s://%(domain)s:%(http_port)s/fancy/pancy/subpath #this will lead to infinite redirects: root_url = /cxf/bpc-httpproxy/httpProxy/grafana Seems something is broken here. We can't set an explicit hostname in grafana and we don't want anything to be redirected neither protocol, hostname or port. ### What did you expect to happen? Seems something is broken here. We can't set an explicit hostname in grafana and we don't want anything to be redirected neither protocol, hostname or port. ### Did this work before? Can't say the explicit version it worked before
