Cannot Connect to Gmail - New Account Wizard

Initial setup
1

Can someone help me fix the Gmail connection? It used to work a long time ago, but it hasn’t since version 10 of eM Client. The synch works fine on my iPhone, so I believe this a bug in eM Client. I have signed in via Google and given all permissions.

If you have completed the add account automatic setup wizard for Google Workspace ok and allowed eM Client access to your Gmail account at the end of the wizard, the above errors can sometimes happen if you have background resident programs interfering with the mail client such as a eg: optionally installed Firewall / Security program, or optionally installed Antivirus program or Vpn or Proxy. So if you have anything like that installed “other than what comes default with the OS” then try completely disabling those to test.
