Hello,
I'm having two problems with Enpass 5.4.1 on a new Gentoo Linux / KDE Plasma 5 system. The initial installation works fine and I can sync and open my wallet without issue.
However, the first problem is that I cannot get a connection to any browser. I've tried Firefox, Chromium, and Vivaldi, with the plugin installed from their respective official sites, and they all give the Enpass connection error page. The only similar thread reporting this problem here is this one, and they mentioned that starting Enpass first, and then the browser, worked for them, however it doesn't work
