Connection retry on Windows to long
if you have no connection on Windows for like 15 or 20 Minutes, the timeout where gajim trys to reconnect gets bigger and bigger. this can lead to a timeout > 15 Minutes.
We have no network manager on Windows, so there is no way to know when we have an internet connection.
either the timeout should be reduced to something like 30 seconds, or if this is too expensive somehow, write a cheap function that checks if we have an internet connection and run that every 30 seconds.
now the timeout gets so big, that people think gajim does not try to reconnect at all.
Steps to reproduce
Deactivate your internet connection for 20 Minutes on Windows
