Cannot send mail via SMTP (version 3.16)

Yeah, I got that you could login normally and phpmailer isn't working.

Try reading the error you got. "Username and password not accepted"...

Are you using two factor authentication?

I mean when i add "phpmailer" as third party library, i can send mail, but the included library from codeigniter i cannot send mail. I've tried 2 months a go and that is normal (on previous version not 3.16) I can send mail.

two factor authentication is off

should I turn it on?

Thank You So Much for attention and help #smile
