"Cannot connect to the mashup data source" - on all dataset this morning

Hello

I received the message on all my dataset this morning:

Cannot connect to the mashup data source. See error details for more information.Hide details

Cluster URI:	WABI-NORTH-EUROPE-redirect.analysis.windows.net

I am connecting to MySQL and Excel files which are on a local server.

Yesterday everything was running smoothly and I have tested MySQL database for problems and there is none. 

Have anybody tried anything similar and knows any solution to the problem? 

I have tried the basic, refreshing in desktop and uploading, 

Thanks

Restarting my gateway helped but did not solve the problem completely. As it shows below, sometimes it updates succesful and other times it fails.

We have the same problem. It randomly fails.

Did you find any solutions?

[AlexanderAT]

No still no solutions.

I have spread my refresh schedules out so all datasets don't refresh at the same time. This might have helped a bit but I still have multiple fails daily with no meaningful error message.
