I've tried searching for this issue but I'm yet to find a solution.
I have Mullvad installed on two machines that both run Debian 12. I have the same in-app settings enabled in Mullvad, but the difference is that on machine #1 whenever I "Disconnect & quit" I am left with no internet connection as if I've just used "Disconnect" and Mullvad is still running. Everything looks fine, it shows my ethernet connection as enabled and everything. But I have to toggle the ethernet connection off and then back on for my internet connection to be restored. I have to do this every time after quitting Mullvad.
On machine #2 if I use "Disconnect & quit" it automatically switches back to my normal connection and I don't have to do the same procedure as on machine #1.
There must be some other setting that I've unintentionally changed on machine #1 for it to act this way, but I can't figure out what it could be. Anyone have any ideas?
