Could not establish a connection with the unity package manager

I tried to launch Unity today and I got this error when I tried to launch it. I disabled my Norton firewall and reinstalled Unity but neither fixed the issue. If you have any solutions, that would be great. Thank you!

 

Hi there,

You'll need to go through the process outlined in the pinned thread: https://forum.unity.com/threads/rea...g-project-issues-with-package-manager.869683/
