I came back to my computer after 12 days of not using it and i find this error on most websites. Was there a new update released recently? Anyhow, this is only on my computer as everything else connected to my router connects to websites just fine. How do I resolve this?

I’ve never seen that message.

You could try removing “/etc/resolv.conf” and then rebooting. That often solves problems with resolving sites. However, you might have a different problem, so I don’t know if this will help.

I fixed it by myself by messing around with network manager. Not exactly sure how I did it but thanks anyway

Try different DNS.
If you’re pointing to your ISP possibly because that’s your default DhCP configuration, ISP DNS are sometimes less than reliable.
Google’s public DNS

Or this public DNS provided by IBM and its anti-malware project
