Hello,
We upgraded our DPA from version 10.1 to 11.1 and although the upgrade completed successfully we are now getting an HTTP STATUS 404 error when we access the DPA site.

Some sever details:
- DPA version - upgraded from 10.1 to 11.1
- Operating system - upgraded from Windows Server 2008 R2 to Windows Server 2012 (this was done just before the DPA upgrade)
- Java version - 1.8.0_161
- Ignite PI Server is running as a Windows service
- DPA database - SQL Server Ent 2012
Any help to resolve this would be much appreciated. Thank you.
