Connection to on premise SQL Server is not possible anymore...

Posted on by Community Power Pla... Microsoft Employee

Hello,

 

Since today, I can't connect to tables or configurate a new connetion to an on premise SQL Server anymore:

 

" Unknown Mashup Exception.     inner exception: InvalidCredentialFormat - Signature does not match "

 

I still use the same credentials like last week...

 

Does anybody have the same issue?

 

Old connections doesn't work, too...

    Hi Tonny,

     

    Could you please check the gateway status at the PowerApp web Portal? My test is OK regarding the connection creation.

    In addition, follow the article below and see if we could find any gateway logs which related to the connections:
