Not want to use my domain parked client, I set up my server, now he has this IP 144.76.138.17 however if I change the primary input for that IP does not work when it arrives on my server, I have to enter the parked whm the domain of the client to my network works there, I believe there should be some configuration of my server when I get to my server already go straight to my network without this parked, this way the client can not map a field alone, it needs me to the parked domain it on my server.
