iOS and MacOS Pangolin clients sudden disconnections from private HTTP resources

Describe the Bug

I've a video streaming service only accessible via a private resource. I can connect to it and start the playback of some video, but after 30s or so the playback stops. I noticed that it's because the private resource is no longer accessible (when reloading I get the private resource page informing that the resource is only accessible using a client). It happens the same without playing any video BTW, that is not a factor, even doing nothing triggers the disconnection.

NOTE I say the client disconnects, but to be precise, what I really mean is that the resource is no longer accessible, the client still reports it's connected.

Tested with both iOS and MacOS clients

Environment

• OS Type & Version: debian
• Pangolin Version: 1.21.1
• Edition (Community or Enterprise): enterprise
• Gerbil Version: gerbil:latest (1.4.3 I guess?)
• Traefik Version: 3.6.25
• Newt Version: 1.16.0
• Client Version: 0.9.1 (iOS) 0.11.0 (MacOS)

To Reproduce

1. setup some private HTTP resource (accessible via HTTPS)
2. connect iOS or MacOS client
3. access the HTTP resource with browser
4. wait for ~30s
5. reload the page in the browser to check that it's still available

Expected Behavior

The private resource should be available as long as the client is connected
