Good Evening Invision Power Board,

Im looking for additional information for this error code for SMTP email sending.

4C143/1 Connection refused

My Website is behind cloudflare, The port in question is Open, and I have triple checked the Credentials.

May I please have some insight on what this error code means, so that I cans see which end I have to fix.

You’ll want to contact your SMTP provider for assistance as that is coming directly from them.

It's the SMTP server side.

Thank you for your replies. I have switched over to icloud to do SMTP. But all three options SSL, TLS, and plaintext still gives me the same connection error code.

Is there something special I have to do with certificates or something?

You can’t use your normal iCloud password. You need to use an app specific password.

Thank you, but i have already tried this as well with the same error code. I switched to outlook now with the same error code.

Is there a server setting i should check for this?
