I have a client that needs support for a configuration issue and this client is using Cloud v7.1. My local DTA have upgraded to 7.2 for a new client so the admin tool isn't backward compatible. I started a VM containing 7.1 and connected the DTA to gain access to the admin tool. After restarting DTA and starting the admin tool, each connection attempt, whether it is using Desktop Apps Authentication or DW authentication, I receive the same error as evident in the screenshot provided. I can access the web client as well as configurations, but, not the admin tool.
Session not registered!
Has anyone seen this and been able to resolve it?
