I have had Gmail POP3 polling running since January using the App password method. No issues and all has been going great.
I upgraded from 3.5.0.beta7-dev to 3.5.0.beta8-dev. I immediately received the following error in my admin panel:
Connection to the POP3 server is failing with an authentication error. Please check your POP3 settings.
I have done the following:
- Checked everything with Gmail. No issues visible.
- Recreated a new app password. The original and the new one does not work.
Any suggestions on how to troubleshoot or do more investigations to determine the issue?
thanks in advance.
