On premises Data Gateway Error (Unable to load DLL!!!)

Hi everyone,

just updated OPDG to latest version (3000.6.202) and now all my connected powerapps applications give me this error when trying to access data in SQL Server:

 

An error occurred on the server. Server Response: Not a valid connector response. returning message as is: { "error": { "code": 502, "source": "europe-001.azure-apim.net", "clientRequestId": "ac9dbef5-41be-4763-9109-8159e40c3c8c", "message": "BadGateway", "innerError": { "status": 502, "message": "Unable to load DLL 'Microsoft.PowerBI.DataMovement.Pipeline.XPress9.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

 

Any help appreciated... I'm trying to reinstall previous version in the mean time.

 

Thanks,

Cris

    UPDATE: I've reinstalled June update and restarted the server. Now it works.
