It has been 3 days since I can add new Datasources, using the SQL connector and an On Premise Data gateway. Existing connections work normally, but if I want to add a new one, I get the following error:
It connects to the SQL on premise, it retrieves the tables and views, even monitoring the SQL Server through the Profiler, I see that the queries arrive that return the metadata of the columns of the tables, but when it clicks accept, I cannot retrieve the data.
The problem is with any SQL server and with any table or view.
My environment and On Premise DataGateway is in "Brazil South" region
Sorry, not a solution but I have the exact same problem. Exactly the same error and time of when the error started with the same data source. Hopefully this gets some attention. It's not what you probably wanted for your reply but it's nice knowing you're not alone here.
I'm up and running now. I'm embarrassed to say that I had to switch from Edge to Chrome and it started working again. I then deleted my cookies and website data from Edge and I'm back up and running in Edge too.
