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?

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