    Sometimes i am getting connection errors also. which is related to IsSMTP function.
    Please suggest some solution.

    Hi,

    From the debug log, it seems you’ve incorrectly used the constants. Usually, it should be like:

    define( 'WPMS_SMTP_HOST', 'smtp.mailtrap.io' );

    Perhaps the value of the constant is generated from the environment variable and it is not processed correctly. Could you please let me know the actual string you used to define a host constant from their wp-config.php?

    Thanks!

    Hi,

    The error seems to be due to the wrong SMTP configurations such as the wrong port. SSL operation failed can be due to server presenting an invalid or expired certificate. You will need to consult your hosting provider support to get correct SMTP configurations and the certificate.

    I hope this helps!
