I have 2 installation of prestashop:
and
I set up emails to smtp.gmail.com:465, TLS, email/password.
On the first installation it works, on the second instaltion it fails with Expected response code 220 but got code “”, with message “
Note: I set up two step verification and app password, I verified it is working with the first installation.
Please help.
Solution: change the Encryption to SSL
In prestashop admin > Advanced Parameters > E-mail
check Set my own SMTP parameters (for advanced users ONLY)
Fill the SMTP fileds
SMTP server: smtp.gmail.com
SMTP username: <****>
SMTP password: <****>
Encryption: SSL
Port: 465
