Add possibility to use a domain name instead of an IP in the Remote Access-checker

I’m using an nginx reverse-proxy to make my plex server available on the internet. Because I have more services running on my IP under port 443 I’m using server_names. So when you enter a subdomain the browser knows where the right service is (in this case plex). So far so good, that’s all working.
But the Settings > Remote-Access checker is only using the public IP to check if plex is reachable. Since it’s using the public ip, it gets forwarded to another service.

So my feature request would be the possibility to replace the public IP with a (sub)domain.

Oh, so it’s actually not possible? I just installed PMS to my NAS behind reverse proxy and I was wondering… Such a simple feature could be added in a notime.

Everything seems to be working. It’s just mildly infuriating to see the red cross.

2021 clean-up: implemented (Settings > [Server Name] > Network > Custom Server Access URLs)
