Over the weekend one of our Powerapps appliactions stopped working we are running Power apps SQL connector through a on premises gateway to SQL Server 2012, the gateway seem to be fine the PowerBI reports runlike nothing has changed.
When we go to the powerapps web application and test the connection we get an error
"Credentials are missing or not valid. inner exception: Credentials are required to connect to the SQL source."
but the it was working 5 days ago
The Gateway log says
Non-gateway exception encountered in activity scope: Microsoft.Data.Mashup.MashupCredentialException (0x80004005): Credentials are required to connect to the SQL source.
We are using the correct login details into the connector it is like it is not passing them on the the server when trying to connect?
Anyone had this issue or know where to start looking
Solved! Go to Solution.
Reporting back in from yesterdays outage, all seems to be well, I was able to add SQL connections without any errors this time around.
It would be interesting to know what happened. It's always hard to know how much to reveal about one's internal processes to customers, but this does seem like a pretty big thing (named instances) to have slipped by QC and regression testing. We've all let things like this slip by, and it's helpful and humanizing sometimes to reveal where the lapse happened and why.
We seem to have an new but simmilar problem now
Invalid Mashup Expression using supplied values. inner exception: An error happened while reading data from the provider: 'Instance failure.'
Please can you check this
I had an issue connecting this morning but did a restart of the On-Premise Data Gateway and everything's back up. Might be worth a try?
