wcf AddressAlreadyInUseException

I already viewed those posts: wcf System.ServiceModel.AddressAlreadyInUseException, Windows Service hosted WCF over HTTPS, Getting AddressAlreadyInUseException after upgrading to .NET 4.5, none of them solve my problem. I have several wcf services in .net 4.5. All of them are in the same Address, i´m getting this exception in the WCF Service host:

System.ServiceModel.AddressAlreadyInUseException: HTTP could not register URL https://+:443/mafawcf01/ServicioAddin.svc/ because TCP port 443 is being used by another application. ---> System.Net.HttpListenerException: The process cannot access the file because it is being used by another process

I already have the port reserved with this comand:

netsh http add urlacl url=https://+:443/MafaWCF01

And also a certificate associated to the port:

netsh http add sslcert ipport=0.0.0.0:443 certhash={some cert hash} appid={some appid}

do you need any additional information?
