Hello ExpertWebWorld! We apologize for the delay in response, as we've received a higher volume of forum posts than we typically experience.

My suggestion would have been to check if the domain had been placed in /etc/manualmx, although it seems you have already identified the issue. I'm glad to hear that you were able to resolve the issue! I'll go ahead and mark this thread as solved for now. If you have any other questions or concerns, please let us know!

Thank you for choosing cPanel!
