Error sending emails

[VeronicaH]

I used the SMTP Configuration to send emails, it worked but i changed my password from gsuite and now Prestashop it's not sending any email. 

I configured it with the new password and i recived the test email:

But when i recived a order, i have no notification to it and the costumer not recive email neither. 

In the logs, i find this error: 

 

If i change the configuration to PHP's mail() function, it say a test email has been sent, but i no recive it in my mail.
