What could be the cause of "Failed to connect to yer.dl.sourceforge.net port 443"

I am trying to install nvidia-container-toolkit, but I’m encountering this error for the past week. What could be the issue?

yay -S nvidia-container-toolkit                                                                      ✔

I would suspect the firewall is blocking the port.

I have used VPN connected to the US server and it worked fine. Currently I’m in Armenia. What does that mean?

There is a firewall program on EndeavourOS. It may be blocking the port. You’ll have to look at the wiki and check. I’ don’t know what your issue is. If you are using a vpn it could also be something to do with that.
