Connecting to self hosted jitsi crashes native app

Description:

We recently set up an own jitsi server and connected it to Rocketchat 3.7.1.

Now every time we start a video call, rocketchat native app goes gray and shows the following error:

Restarting the App fixes the problem, the call however is lost.

Steps to reproduce:

1. Setup your own jitsi server instead of using meet.jit.si
2. Set it as default jitsi server in configuration
3. Start a call

Expected behavior:

The call should be available, and Rocketchat Native App should keep running.

Actual behavior:

As shown in description

Additional context

Relevant logs:

No source file, test, or entry point is identified. Reproduce the crash using a self-hosted Jitsi server configured as default with Rocket.Chat Server 3.7.1 and the native app on OS X, then inspect the native app's error details; done means a video call starts without the app turning gray or requiring a restart.
