On latest Gateway we are getting DM_ErrorDetailNameCode_UnderlyingHResult: -2147467259

[KevinM]

When we updated our Gateways on report that works on the old system began to have problems updating.  We are getting this error but not everytime.  Sometimes the report will run.  I looked in the logs and cannot find an error but I can see the job processing but not completing.  

Any ideas of why this is not working on the Gateway version 3000.3.138 (2019-04-09)

Hi there

It would appear that there might be connectivity issues between your Gateway Server and your data source?

You could enable the verbose logging on your Gateway server to see what is happening during the refresh.
