Everything is set up correctly under 'Setup > Servers'
I have also manually created packages on WHMCS entering package name only (same names as packages on WHM).
When attempting to Import Domains from cPanel/WHM I get the following error message:
Connection Error
connect() timed out! (Code 28) - Check IP/Blocked Firewall Ports
Attempt to sign up new domains and hosting accounts (automated setup) via WHMCS client portal also fail, nothing happens in WHM.
I seem to be doing something wrong, but I have no idea what.. It would be great if someone could help me, maybe I'm just missing some important step?
