I have a Samsung Galaxy A10s with Android 11 One UI 3. Recently there was a problem: VNC viewers do not work. I enter, for example, localhost:1 (I want to connect to the Termux VNC server), I connect, and the connection window hangs indefinitely, and then a timeout appears. And so with any VNC viewers (I tried AVNC, bVNC, VNC Viewer). I tried AVNC, bVNC, VNC Viewer, change localhost:1 to localhost:5901, but nothing works. Help me please!
Translated by Google Translate from Russian
The problem was solved by allowing background activity in the Termux settings.
