I have been able to get everything set up and it is running great. I'm using the letsencrypt docker for reverse proxy and everything works.
The only issue I have, is that I have no problem adding a link to another docker container from my server to the homepage of heimdall, provided it is set up as a subfolder, however I can not figure out how, or if its even possible, to add a link to something set up as a subdomain.
For example if something was set up as myserveraddresss.com/plex I would just add /plex in heimdall to link it.
But if I wanted to add plex.myserveraddress.com it doesn't really have the functionality to add something this way.
I just want to be sure I'm not missing something obvious, and if not maybe it could be added in future releases to use subdomains as well as subfolders.
Thanks.
