I have the same problem since a few days ago.
I have activated “less secured apps” and setup the SMTP settings as follows:
Host name: smtp.gmail.com
Use secure connection (STARTTLS): YES
Here is the message I have:
It looks like there was a problem reaching your SMTP service
Error Message The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Authentication Required. Learn more at

What do I do wrong?
Thanks for your help
