Internet Connection Issue

Go to System Preferences->Network, click Wifi (or Ethernet, if that is what you use to connect), and then

click Advanced... and then click DNS.

What do you see?

Under de Advanced part of System Preferences->Network, check the Proxies tab. Normally there should be no proxies set.

That very light grey is normal and indicates that this is the dns that your mac picked up automatically from your router.

You can try restarting your router and see if that helps. You can also add one of the public DNS servers in there.

The easiest to remember is 8.8.8.8 (that’s from Google), but freedns also provides public DNS servers.

To add one, click + and type the IP. It will appear in black. If you remove any additional DNS servers your mac will revert back to the default one you see now.

Before trying something more drastic: restart your mac in Safe Mode.

Do you have internet access while in Safe Mode?

If you do, then you may have some form of adware or other third party software blocking access.

Good.

Then you can download Etrecheck and post its report.

Hopefully, we may be able to find something in it.

More than one antivirus app - This computer has multiple antivirus apps installed.

Uninstall Symantec and Webroot, and do not install a third party antivirus software.

They conflict with the built-in security - and with one another - and offer zero protection.

In all likelihood they are the cause of your problem.

Read this excellent post about keeping your mac secure:

Effective defenses against malware and other threats

I’m just going to throw this out there…. I apparently turned on (private relay-beta in iCloud) I’m sure it’s not your issue but I just thought it was worth mentioning. Hope you get it working again.

You're right. Not only it is not needed, it is a bad piece of software that causes system slowdowns and instability.

The best way to uninstall is to follow their own instructions. If it comes with an uninstaller program, use it. Otherwise check with them for how to properly uninstall. A quick search online should get you there, like "uninstall norton mac"
