I am trying to make the /ConnectApp api call in Postman to get a connection credential, however I keep getting a 500 error that says I am not logged in despite providing my login credentials in the POST call. Is there another step or something that I am missing?

Hi,
would it be possible for a cloud connected onPrem System?
Running ConnectApp and then any Webservice Call works fine on local DNS but on the could one: ***.on.dataminer.services i also get the 500.
