Hello everyone! I’ve delivered the bulk of my hyper-strict deadline, so I’m just waiting on some feedback on the final set (3 out of 4 have passed). So, time is starting to free up for me to finally get some shut-eye and return to help. And - of course - re-engage in the LMS.
@Mike19 - I responded to your issue via a reply to the direct message you sent me. Your issue appears to be due to the concurrent installation of ProtonVPN and NordVPN. Those two don’t really like each other. 
@Margo - The ProtonVPN commands are universal. I use it for Arch and RHEL (Red Hat Enterprise Linux), which utilize different package managers.
Also, the solution posted above is temporary. I have included the permanent one in the link below:
Also, if you ever reboot or shutdown without disconnecting ProtonVPN, you will encounter the connectivity issue again. It’s because ProtonVPN doesn’t automatically shutdown its IPV6 leak protection, which is what hinders your system’s name resolution, thus making it look like you have no Internet (while in reality you do have).
