Scheduled and Ondemand Refresh fails

[sumathymohan]

For the past 1 week, the Scheduled and Ondemand Refresh fails with the error message 'Unable to connect to the data source undefined'.  There is no problem in connecting to the data source.  The refresh process runs for a more than a hour and finally fails with the error message.  When I click on the show error message, I do get the below message as in the screenshot.  With this message, I am not sure what's the real cause of the error.  Kindly help to revert to me on this issue.  If you need any more details, please do let me know, I can provide.  Thanks.

Hi,

With the same connection and the same settings, the scheduled refresh is running successfully for a couple of times.

When the refresh fails, I could not get the proper error message from the gateway logs too.  Below is the partial error logs from the Gateway.  Does anyone have an idea on how to resolve this issue.

Hi @sumathymohan ,

We do have customers who have had similar experiences to yours, and this is a problem caused by the gateway version.
Can you provide us with your gateway version for further confirmation?

Best regards.

Thanks for the response.  Gateway version: 3000.146.10.  Please let me know, if you need any other information. This has to be resolved asap as this issue is affecting our business.

Hi @v-xiaoyan-msft ,

Any update on this?  The refresh is still failing everyday with the same error.  Can you kindly look into this issue?

Thank you.

I have updated the Gateway to Version 3000.154.3 and I still do have the refresh error.  Can you please look into this issue?

Thanks @v-xiaoyan-msft for your response.

I tried to create a Support Ticket but after I fill in all the information on the support request and click on the Submit button, nothing happens.  It just stucks there and no error displayed also.

Clicking on submit button doesn't submit the page or throw any error.  Now I have no way to contact the customer support

Edit:

After I changed the Issue Date and time to current time, I was able to submit the Support Request.  Not sure if there is a bug in the Support ticket creation.
