Can't login anywhere

Hi,

Impossible to get a successful connection test, with any credential.
I always get the quivalent of "bad login/password".

My credentials are ok, I tested several from Sendgrid and Custom SMTP servers, all works well with classic Mautic configuration, but once in Random SMTP Bundle, it fails. And yes I did the column number setup.

Mautic 2.16.

Thank you.
