Dear Support,
I have install WP SMTP on wordpress 5.4 and try to connect it to mdeamon mail server.
I have recived error durring test email.
Errror says that could connect to smtp server but cooul not authenticate with the mentioned email abd password. I sure that username an password is correct.
Interestingly, it sometimes works without any changes. For example, with 10 attempts, it works correctly once and gives the above error 9 more times.
Would you please help me?
Regards.
