Sounds like traffic to outside is blocked (firewall, outbound proxy) or other misconfiguration as the agent complains the request is sent, but it never receives a response within before timeout kicks in. What happens when you enter the URL in IE/Edge on the system, https://<That GUID>.resource.mailboxmigration.his.msappproxy.net/EWS/mrsproxy.svc

  we had to create a support ticket and some other engineer worked on it. It was resolved by ms support. I am sorry I am not aware of the solution.

    I had the same error when trying to create a migration batch. It appeared to be the credentials of the account that used to create the Hybrid endpoint. After updating the Endpoint credentials it worked without any errors. Mohkam

Is that response coming from backend (authentication issue) or somewhere in between (blocked by or not authenticating against proxy, etc)
