I’ve read about other having similar problems, but mine is slightly different.
Brave keeps logging me out from my webmail. We use Roundcube Webmail in the family and I am the only one using Brave and also the only one with this problem. Roundcube is the only tab that logs me out, and it does so while the browser is in use. I might be on other tabs or in other programs, but as soon as I switch back to Roundcube, it has logged me out.
VPN is often active, I must use VPN for work. The problem does happen even with VPN disconnected.
Clearing all cached data solves the problem for a while, until next time I have to connect to VPN. I really don’t like clearing the cache all the time.
Restarting browser does not help.
No automatic clearing of cached data enabled.
No secure VPN set in browser
Running Version 1.48.167 Chromium: 110.0.5481.104
These problems started early this year and I just got fed up now. Might be changing preferred browser if I can’t fix this. Not using VPN is unfortunately not an option most of the days. And still, as soon as I’ve been connected, this keeps happening until all cached data is cleared again. Ctrl+shift+del is my new three finger salute… )=
