Hello
I am getting these errors in Graylog
Graylog is configured to send a slack notification based on the events and queries.
Tried restarting the services but it’s not helping. Not able to find anything in the community on this topic.
Graylog version - 4.2.5-1
elasticsearch - 7.16.2
mongodb-org - 4.0.27
