All I get back is an error message of
"Analysis Services Processing Task Error: A Connection cannot be made. Ensure the Server is running"
The server is running, I can process the cube by connecting to the AS instance and right-click processing it.
I can process the cube by running the SSIS task inside of SSDT
Just when I deploy the SSIS package (in Project mode) and then execute it do I get the error message.
SQL Server, SSAS, and SSIS processes are all running under the same account. SSAS is on a separate server from SSIS and SQL if that matters.
