On Premise Gateway / SQL Server DataFlow
When you go to create the dataflow in the service mine auto completed the login details:
Guessing yours isn't doing that?
Things to check:
1) Is the server name you're enterering matched "exactly" with what's in the gateway connection. eg if gateway is setup with servername.domain and you're entering servername it won't work. I think it might even be case sensitive.
2) In the data source setup in manage gateways are you listed as a user of that data source:
It does autopopulate the credentials. I've tried leaving as is, I've tried typing them in. For the server name/database name, I've typed and I've copy pasted. I thought maybe I had typed something funny when I set up the gateway. I literally installed the gateway on the server, set the gateway up on Power BI and then imported a dataflow, changed the parameter values to the new server name. That didn't work so I tried a new dataflow thinking it didn't like the import. I've tried encrypted/not encrypted. I've even tried doing it in a browser on the server itself. I can log in to SQL management studio with the credentials I'm using so I know they're good. I've checked remote connections - that's good.
That's odd. If you have SSMS installed you probably also have sql server profiler installed? If so start a trace on your sql server and then try and connect your data flow. You should hopefully see some activity and a login attempt. Might give some clue.
Other thing to check is the logging in the on premise gateway client.
