[6.12.13] Unable to access Docker containers over custom domain

[Paradonix]

Recently I went ahead and setup my Unraid server and installed a few Docker containers such as Jellyfin. I want to be able to access the WebUI of these containers using my own custom domain, container.home.example.com.

 

I already have a Raspberry Pi running Nginx Proxy Manager as well as Pi-hole. Using Nginx Proxy Manager I'm able to use a wildcard certificate for my internal services. In my Pi-hole I'm adding these domains to my DNS. This works great when trying to access my Unraid server over unraid.home.example.com or my Nginx Proxy Manager over proxy.home.example.com.

 

Unfortunately, accessing my Docker containers running on my Unraid server doesn't work as expected. When navigating to i.e. jellyfin.home.example.com, I get shown the Unraid login page of my server. The DNS and proxy should be configured correctly:
In my Pi-hole DNS settings: jellyfin.home.example.com pointing to my Unraid server

In my Nginx Proxy Manager: Source: jellyfin.home.example.com    Destination: [Unraid server IP]:8096

 

However, when enabling my VPN (Mullvad), I'm suddenly shown the Jellyfin login page, instead of that of my Unraid server, just how I want it to work. However, I want it to also work, when I'm not using a VPN. Note that I have configured my allowed IPs list to exclude my subnet.

 

I hope this is the right place to ask this question, if not, please let me know.

 

I would appreciate any help in fixing this and finding the cause for this issue.

 

Edit:

I have a custom wildcart certificate installed on my Unraid server. Upon removing it, I can no longer access my Unraid server and any containers using their domain, unless I am connected to a VPN.
