Issue with Sonarr loading White Screen via Reverse Proxy

Hi guys,
I registered a domain name, configured my DNS CNAMEs, forwarded the necessary ports, and successfully set up.

Everything seems to be working, I can access all three of my Docker containers from outside my network using my domain name and custom subdomains. However, I’m encountering an issue specifically with Sonarr.

When I try to access Sonarr from outside the network, it prompts me for my username and password as expected, but after logging in, the UI hangs on the loading White Screen and never fully loads.

Strangely, when I access Sonarr from within my network, it loads without any issues. I have also noticed this resembles a white screen issue, as the page seems partially loaded but fails to render the interface properly.

Has anyone experienced this screen issue before or know how to resolve it?

Logs from when you try might shed some light
