Hello,
I am trying to setup SMTP on OSTicket but getting error message while setting as :
"Failed to connect to smtp.gmail.com:465 [SMTP: Invalid response code received from server (code: -1, response: )]"
Below are the version details:
osTicket Version v1.11
Web Server Software: Apache
MySQL Version: 5.7.24
PHP Version: 7.1.27
Please note, we use G.Suite account for email and are using 2 factor authentication on email. So I am using the "App Password" which we generally use in Outlook configuration.
Please suggest for the resolution at the earliest.
