Whatever you do, avoid NORDVPN. The app sucks.
I fell for their ads, subscribed, and after three days I deleted it, removed it from all my devices, and cancelled my account.
From the start I was not able to access some of my favorite sites. Then, on Sunday night, Feb 23, the whole thing went to hell.
I could connect to my wifi but could not connect to the Internet. I live in an apartment and at first I suspected a local area problem. Checked with a couple of neighbors, neither of them had a problem. I booted up one of my laptops that did not have NordVPN installed and it worked fine.
After restarting my computer a couple of times I was able to uninstall NordVPN and the system now works perfectly.
