Certain Android devices cannot connect to AppWarp servers,Connection Error 5

Question

For some reason, on my personal Android device, i can connect completely fine, and not get any connection error when using connectWithUsername(), but when i try to do it with another android device and my virtual device, it always gives me result code 5 Connection Error, when trying to use connectWithUsername.

My device which is able to connect is a Samsung galaxy j7 prime. Devices which wont work are a Samsung galaxy j7 pro and my virtual device which is a Pixel 2.

Thank you
