flarum.ERROR: Swift_TransportException: Connection could not be established with host pop.turkticaret.net :stream_socket_client(): Unable to connect to ssl://pop.turkticaret.net:995 (Connection refused) in /data/host/skeleton/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:261
Are you sure that these are the correct configuration settings? The pop in the hostname suggests that it is the POP protocol instead of SMTP, which would be the reason why it’s not working.
As a side note, I see that you have specified some Mailgun settings. If that’s what you want to use instead of SMTP, please select the mailgun
driver instead of smtp
and configure the necessary settings.
