Auto Refresh not Working


Non of the queries are auto refreshing. I am specifically referring to the queries and not the dashboards. The queries work and update if manually triggered. Restarting all the redash processes has no effect. In the system status page the Last Refresh row has not date of time. Both the ‘IN PROGRESS’ and ‘WAITING’ queues are empty. The ‘DONE’ page lists all the queries that were manually triggered.

Where do I start looking for the problem?


While troubleshooting the above-mentioned problem I stumbled upon the following error in the log files:

@HenroRitchie, I have the same problem and the same errors in /opt/redash/logs/celery_error.log.

Were you able to solve it?
