• Your Rocket.Chat Experimental app version: Official 4.1.0.2095, Experimental 4.2.0
• Your Rocket.Chat server version: 3.0.0 and 2.3.0
• Device (or Simulator) you're running with: Samsung Galaxy JS, HomTom HT72, Android 6.0.1 and Android 7.

Once in a while when I try to open an app or click on a push message, the app launches but prompts me to type in the server address and log in, although I did not log out previously. Difficult to reproduce as it seems to happen without any rule.
Sometimes it loads the server and channels before logging me out again.
