I can´t access EAC by CAS name server

Hi people,

I´ve just installed my new Exchange 2013 SP1 environment in a new domain.

I´ve installed two Mailbox server and two Client Access servers, I´ve started the installation with two mailbox serves and to continue I´ve installed the Client Access servers. When I finished the installation in each server I restarted it.

Now, my problema is the Access to Exchange Administration Center.

I´m trying with https://servercas1.domain.local/ecp orhttps://servercas2.domain.local/ecp

In both cases, Internet explorer sais "this page can´t be displayed"

I´ve checked the Ecpvirtualdirectory in PowerShell, and internal url is correct: https://servercas1.domain.local/ecp in the first CAS andhttps://servercas2.domain.local/ecp in the second CAS.

I´ve tried Access by IP, but with the same result...

Finally, I´ve tried the Access with https://localhost/ecp and it Works!

But... I want to Access by name, no by localhost....

Someone knows why I can´t Access by name??

I understand the Access to EAC is only possible through the CAS, because in the Mailbox doesnt work it, right?

Thanks and Best regards.
