Lost connecting to SQL Server Database

Hi all,

 

Hoping you can help me.  I've been connecting to a data source for some time.  And all of a sudden it has just stopped on me.

 

I have tried going in to Source cog in the Queries pane and reconnecting to SQL Server database.  Entering Server name and database name. But it won't re-establish it's connection.

 

The error I keep getting is as follows ....

 

DataSource.Error: Microsoft SQL: A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.)
Details:
DataSourceKind=SQL
DataSourcePath=tc-sql01\sql2008;Venu2
Message=A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.)
Number=-2146893019
Class=20

 

does anybody have any advice for me on how I can resestablish the connection please? I'd be eternally grateful.

 

Many thanks

Hi @LeighMacKay 

From the error message, it seems it's the error from Gateway, right?

If so, there is a similar post which was solved, you can check whether the solution helps you or not.

From this thread, it indicates that you may re-select the proper credential type and re-enter the credential.

 

Besides this, there may be some useful steps to check the connection to SQL Server.

Check the connection from SQL Server side:  Use Microsoft SQL Server Management Studio to connect to SQL Server

Some tips on how to troubleshoot loss of connection with SQL server.

 

Best Regards
