i have 2 mapped domains already working, i want to add

Hi, i have 2 mapped domains already working, i want to add a new mapped domain but doesn't change to valid state, its invalid all the time and when i try to open the domain URL it opens the cpanel 404 error page.
I have the domain parked in the same cpanel user account of the other 2 working mapped domains.

I have reviewed the DNS records and compared also to the other 2 working domain DNS records and everything looks fine.

The name servers are ok, the ip address also, i have deactivated and activated domain mapping plugin but didn't fixed .

Im lost of what could be blocking the mapping of domain....
