App Store, iTunes Store, or other Apple services - If you can't connect


Are you running any anti - virus programs? Using a VPN?


Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Also try the Safe Mode.

Safe Mode - About.       


If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply.

None of the fixes you mentioned have worked. Since my late 2015 21.5" iMac was upgraded to Catalina it has been scrogged. It is about ready for the dumpster, thanks to Apple. I can log in to App store, iTunes, Support Community et.al. from my 2 other iMacs and 2 iPads with no issue. Seems that when Apple uses the App store to update an app I can't do it.
