Here are a couple of things you can try...

  1. Run IISRESET on each Exchange server
  2. Restart each Exchange server
  3. Ensure port 80 and 443 are open to the Exchange server you configured for hybrid from outside of your environment

These Endpoint s are important because you will be using them for migrating the mailbox with MRSproxy so you need to make sure you have MRSproxy enabled on hybrid server so make sure this FQDN points to your CAS servers where you have MRSproxy enabled
