Android http connection problem

[syd45]

In the Android version, http connections often appear as follows。This problem occurs almost every day on both Android devices

This problem can not be solved by manually clicking "stop" and then clicking “start”, it still can't connect to the server, you need to manually log out and then log in again.Only then can the problem be truly solved. (The phone can always serve web pages correctly, but the app cannot connect correctly)

In addition, my Android client is the latest version 3.0
