As far as I know ProtonVPN provides its own DNS when a client is connected to their servers, and I thought that Qubes OS was trying to use another DNS provider, and I thought this was the source of the problem. I’m not sure
I used ping protonvpn.com and error ping: protonvpn.com: Temporary failure in name resolution occured. So I thought the issue was with DNS.
Sorry if something I say is inaccurate, I’m new to Qubes OS.
Thank you and all other Qubes OS team members.
That’s certainly an issue with DNS.
I don’t use ProtonVPN.
I’ll get back to you tomorrow.
