## Talk app

**Talk app version:** 22.0.10

**Custom Signaling server configured:** no

**Custom TURN server configured:** yes, tried it without

**Custom STUN server configured:** yes, tried it without


## Browser

**Microphone available:** yes

**Camera available:** yes

**Operating system:** macOS

**Browser name:** Zen

**Browser version:** 1.19.5b (Firefox 149.0) (aarch64)

### Browser log

In the network log the URL `/ocs/v2.php/apps/spreed/api/v3/signaling/$ROOM_ID` is called repeatedly.
The first time the response is without issues and contains JSON.
All subsequent requests contain this:
```html
<html><body><h1>504 Gateway Time-out</h1>
The server didn't respond in time.
</body></html>
```
The only difference I could find is the Header `TE: trailers`.
