Trilium page does not load over Reverse Proxy (Nginx and Caddy)

[Y0SIHiii]

Hello everyone,

I've been struggling with this issue for days now and, unfortunately, haven't been able to find a direct solution.

Problem:
I have set up a Trilium CT on my Proxmox server using Docker. Locally, everything works perfectly. However, when I try to access it through my network via a WireGuard site-to-site connection and configure the proxy host in Nginx, I encounter an issue: I reach the Trilium login screen, but after logging in, the screen remains blank and does not load.

I also tried using Caddy, as it supports WebSockets, but the result was exactly the same.

All settings are at their default values.

I’d really appreciate any help or insights on this!

Many thanks in advance.
