I am trying to setup a Google Workspace gmail account in Mautic 4 Mail Send Settings, my PHP version is 7.4.
I have tried an app password and the login usual setup but did not help.
This is the error I get:
Failed to authenticate on SMTP server with username “firstname.lastname@example.org” using 3 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code “535”, with message "535-5.7.8 Username and Password not accepted
Any help please!
