Describe the Bug

Hey there,

I just recently switched to Pangolin as my reverse proxy and outsourced the connection to a small VPS. So far so good, I was able to implement all ressources and services. They are all accessible over the Browser and are working fine.

The weird part is, that I noticed a playback issue in the emby app (I have to wait like 30 seconds for the playback to start) but everything else is working normal like browsing. The playback in the emby app takes a while until it starts. It is not a transcoding issue or anything, because the server does get the request but is waiting for something. You can see this in the embyserver logs at timestamp 2025-10-27 16:51:18.412.
The response finally arrives at 2025-10-27 16:51:48.907

Emby Android logs are also attached. (Time is off by one hour)

EDIT: Attachements see in my next comment

I sadly did not find any Pangolin logs. Under config/logs the directory is empty.

Plex does not even recognize the server anymore (In the Android App).
Over the Browser, both services are readily accessible and are working with full performance.

As soon as I turn on my VPN and the traffic is routed over my internal reverse proxy (Caddy), everything is working as it should again. No 30 second delay.

So the weird thing is, why does the reverse proxy work totally fine in a browser with those services, but as soon as I use the apps of those services, they suddenly work slow or not at all?

This behavior sadly started with Pangolin, so I first start to look here. Also as it is happening with Plex and Emby.

I appreciate any ideas, because currently I am quite stuck...

Best reegards,
Kevin
