@joefinnerty_123,

Use any of the freely available SMTP plugins and then try sending emails via that and let us know if that works.

Test directly from plugin WP Mail SMTP using php mail worked.

Test directly from plugin WP Mail SMTP using SMTP errored.(See Below)

In both cases PHP MAIL/SMTP)Test from email subscribers plugin says it was sent but wasn’t.

@joefinnerty_123,

For 504 gateway error, you would need to contact your Host Provider / System Administrator.

Also, this is a public forum. So, kindly do not put sensitive information here (example, your cron url).

cron doesn’t seem to work either

Because you have disabled cron via this line : define('DISABLE_WP_CRON', 'true');

Can you please tell us why you have used this : define('ALTERNATE_WP_CRON', true);

For further communication on this, please write to us from here.
