Hello,

Could you verify if any firewall rules are blocking access to port 465 on this system? This document should help:

Thank you.

No, I have confirmed firewall rules are not blocking the port 465.

It's possible your provider has blocked that port as well. You may want to contact them to verify if that's the case. If not, feel free to open a support ticket using the link in my signature so we can take a closer look. You can post the ticket number here so we can update this thread with the outcome.

Thank you.
