I can't think of what the problem is, I already tried restarting my network adapter

On the afflicted machine, what is the terminal output of

sudo lshw -C network

?

Are you dual booting WIndows?
I ask because in this post:

Windows can also hold onto the network card preventing it from initializing during GNuLinux Init.
So a user must boot into Windows, release the network, fully shutdown - then bott into GnuLinux.

If you can ping an IP address (8.8.8.8 and 8.8.4.4 in your case), but you cannot ping a domain name (google in your case), that's usually indicative of a failure in DNS resolution.

That failure can be either internal to your machine, or it may be that the DNS server(s) you're using have either gone down or are under (D)DoS attack.

First check that your firewall is allowing DNS communication via port 53. The easiest way of doing that is to simply disable your firewall temporarily, see if you can ping a domain name, then re-enable the firewall.

Then check that your internal DNS resolver is running. In most cases, that's going to be Bind.

If it is running, try restarting it.

Then change to different DNS server(s) you're using to see if that's the problem.

No dual boot, only Zorin

I don't have any firewall enabled
I try systemctl restart systemd-resolved
This is the output for systemctl status systemd-resolved

I just find the solution in this post, that send me to this other one, seems that the problem was with Proton VPN, I don't mentioned before because I already had deleted a Proton connection using nm-connection-editor. Thanks a lot for the help
