Cant access ECP or EAC on new Exchange 2013 Mailbox role deployment

I am starting to migrate our Exchange 2010 system to Exchange 2013.  Currently we have two 2010 mailbox roles servers and two 2010 CAS servers.  I followed the migration guide I installed a 2013 mailbox role server and a 2013 CAS server.  On the mailbox role I can not access EAC or ECP.  I always get a 404.0 not found if i try the https://servername:444/ecp I get a 400 bad request error.  I have tried multiple solutions found online but no joy.  The Exchange management shell seems to be working correctly and if I log into the 2013 Cas server admin console it works and sees the 2010 and 2013 mailbox roles any ideas?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That's expected as the ECP/EAP roles reside on the CAS server, not the mailbox server.

So I shouldn't worry about and either do the administration from the CAS EAC?
