Using Flask-Mail to send Email through Gmail- socket.gaierr
I have the following settings that work for me
app.config['MAIL_SERVER']='smtp.gmail.com'app.config['MAIL_PORT'] = 465app.config['MAIL_USERNAME'] = 'xx@gmail.com'app.config['MAIL_PASSWORD'] = 'xx;'app.config['MAIL_USE_TLS'] = Falseapp.config['MAIL_USE_SSL'] = TrueNote that MAIL_USE_TLS parameter that I have. Also not sure if it matters but your MAIL_SERVER is set to smtp.google.com while mine is smtp.gmail.com.
EDIT: As confirmed, the primary issue was that your smtp host was incorrectly set. It should always be smtp.gmail.com
