Google Gmail access via POP3 gives ERR [SYS/TEMP]

Have you ever received this error from

-ERR [SYS/TEMP] Temporary system problem. Please try again later.

I did.  It turns out that if you try to use SSL on port 995 and login using the USER and PASS commands, you will receive this error if you either: 1. tried to base64 encode your user/password data or 2. you did not setup an “App password” and use it instead of your normal password.

You can setup an “App password” here

That’s it for now.  Good luck!
