Issue: VS402335: The timeout period (30 seconds) elapsed prior to completion of the query or the server is not responding.
Solution: This issue occurs when the query takes time longer than usual to complete. This is mostly an intermittent issue and if this issue occurs try in incognito or Private mode. And also this might occur when there is an availability degradation.Refresh the page multiple times so that your query gets completed
This error may occur during loading of Backlogs or Widgets or creating workitem charts etc.,
