Sending via gmail failed

[Ulawun]

Hello Mailers,
When I check out the github demo code
(sending a mail via gmail),
I get attached error.
I successfully logged in at google and checked again -> same error.
Any ideas please ?
Thanks.

You may need to "Allow Less Secure Apps" in your gmail account (it's all the way at the bottom). You also may need to "Allow access to your Google account". See details about using Gmail here.

Allow access to your google account above helped after hours of messing around with allow less secure apps.
