MRS connection fails migrating to Office365

I am trying to migrate a client from Exchange 2010 on a SBS2011 server to Office365. I have the directory sync working and it created the users in Office 365, but it does not create the mailboxes. I am under the impression that they will be created when the user is migrated.

I go into migrate the user in Office 365 Exchange and I select the "Remote move migration (supported by Exchange Server 2010 and later versions)", then select the user (just one as a test) then I put in admin creds and the server address. It fails connecting the the MRS Proxy. I see on the server that the Mailbox replication service is running and I have gone over everything to make sure the MRSProxy is enabled. But it keeps failing to connect.

How can I confirm that it is running? The site passes for the EWS, and outlook.

    I am thinking that you may need to cycle the services on the each of the CAS servers

    The issue was the SSL cert for the client expired. After I renewed the SSL cert for them the server tested clean. This client is new to us and they mistaken with the actual configuration of their servers. In the end they opted to go with a staged migration since they didn't have the resources to fully configure a hybrid environment.
