Please specify how to connect.

[Anonymous]

So I needed to make some changes in the advanced editor of a dataflow entity. I do this every month-end and never had problems, this month at the part where I get the error; "Please specify how to connect.", when I click on configure connection and sign in, it loads for a few seconds and just gives the error again. 

Does anyone know why this would happen? It accepts the login details, loads and gives the same error. My gateway is running as I do this and up to date. Is there some error that the service is not just showing me that is preventing it from signing in?

Which datasource you needed to edit or add? I can reproduce the error, but reason is unknown I will keep consult the issue internally. You may take a look at the solution in this post: (SAP HANA)

Thank you for the response, I will check it out. 

Just to let you know, it seems the problem was with the data source. The structure changed and I did not notice and it seems the error was misleading since it had no problem signing in and excepting the changes when the queries were fixed. Just not sure why it did not give errors in relation to the problem?
