while installing SQL Server Reporting Services by AX installer I got below error. I recently made my machine to point to a new server.
“The AOS ‘MicrosoftDynamicsAX@servername@portnum’ cannot be reached. Setup cannot continue. Verify that you entered the correct server information and that the AOS service is running.”
It was clearly pointing to the old server. Then I tried to check the Microsoft AX server configuration which contained my new server path, also checked the client configuration which was again pointing to the new server. However the ‘Business proxy account’ was still pointing to the old server. So changed that to the new server and it worked like a charm :)
