I am trying to add a realtime service connection using: docs.microsoft.com/.../extend-commerce-data-exchange
However I get the following error when testing it: A connection to headquarters could not be established. This may be due to Retail Real-time Service is not running properly or the trusted certificate used by Real-time Service is missing or expired
Then I clicked on Picking and Receiving in CloudPOS because that is a standard realtime connection and I get the same error.
So is there something special I need to do on my Dev box which is cloud -hosted, thus I have admin rights on it, to get realtime service to work?
