Weirdest damn thing, occasionally my network connectivity was being lost. Not the wifi signal, but just the route to the internet. I finally realized today it happens whenever I do a fresh boot (i.e. first time after system boot) of Heroic Games Launcher.

I am running OpenSuse Tumbleweed and using the Heroic Flatpak. Any idea how I would debug what the heck is going on so I can give a bug report to the Flatpak maintainers? I was poking around /var/log but didn't see anything interesting.

Edit: Correction, it brings down my network on every single launch, not just from a fresh boot. The network eventually comes back up, but it blips for a good few minutes.

Message that pops up in KDE is "This device appears to be connected to a network but is unable to reach the internet. " and trying to open websites leads to an error page.
