Hello Musak01,
We see you're having issues with accessing websites across all browsers on your Mac. We'd be happy to help.
This page here helps to detail some steps to take when sites aren't loading in Safari: If Safari on Mac doesn't open a webpage or isn’t working as expected
Be sure to also check to see if your Mac's system date and time are fully accurate. This will be in System Preferences > Date & Time.
If you're using any VPNs, antivirus, or other security software, try temporarily uninstalling them fully from the Mac. This will just quickly help to rule them out from affecting things.
Cheers.
