Linux

I'm on Fedora KDE Plasma spin (40 and 6.1 respectively) and I need help with Proton VPN. In Discover, there is an app available for Proton, however, it is not officially supported (even though it's put out by Proton AG) AND it's a flatpak, which means it's sandboxed, so, problems. I have an account with Proton, and love their email and password manager, but I'm currently only on a free account because, 1.) I don't have the money right now, and, 2.) I want to make sure it works before I spend money on it.

So the problem is this: It works well enough, but after a short while (somewhere around 10-30 minutes) it just loses communication. I'm still connected and online, but nothing will load, no data is being transferred one way or the other; it just conks out. It also has this issue where if I switch servers "too often", it will start asking for a password every time I try to connect to a server even though I'm already logged in, and my password doesn't work for it. It will do this until I log out of Proton and reboot my machine, and even then it sometimes stays stuck in this asking for a password state.

I have talked with Proton's support about this, but the only thing they will tell me is that it's not supported because they only support GNOME Fedora and a handful of other distros. Well, I'm not switching distros right now, or anytime soon. They do have a way to use OpenVPN with their service, but it's quite convoluted and my brain starts to melt when I try to figure it out. Plus, Proton is the only VPN that comes up in Discover.

Would Flatseal fix my issues, and if so, how do I configure it? If not, how can I get it, or another version or whatever? I just want privacy, dammit! If you can, please provide clear instructions or a link to clear instructions.

Thank you in advance!
