Your SMTP username and/or password are incorrect. There's a URL in the error to get more information.

 

[Benjamin Hallman]

They are right, I have checked this multiple times. Any other ideas... I really need to get this fixed.

 

[Jeremy P]

As Mike suggested, visit the URL to get more information. The username and password might be technically correct but are not being recognized as valid.

If the Google account has 2FA enabled, you will need to use an App password. Otherwise try the other steps listed at that link, and if nothing else works you may need to use the option to allow less secure apps to access your account.
