Sending email through C # using a custom domain from gmail

Question

So ... I have a project in Visual Studio 2015, encoded in C #, which sends emails, everything works fine with commom gmails and hotmails, SSL enabled, ports, etc. They can send emails and authentication.

But now my studio has a custom gmail domain as such [e-mail] , so I used the same properties as for sending normal gmail.

And then I get the 5.1.1 error message. The SMTP server requires a secure connection or the client failed authentication. All other gmails work.

Do I need to change the SMTP server? Port? Tried everything so far ... no help.

PS: Yes, I have included low-level applications in gmail.
