https://osquery.slack.com/archives/C01DXJL16D8/p1675166898239869 Any idea on this one. I have an error that node key is missing and secret not found
also tried the re-installing agent, still nothing
Also why so many err for requires fleet premium on upgrade
the fleet premium errors are a red herring, those are expected as they signal the Fleet Desktop app that some features are disabled. I'd say let's focus on the enroll secret errors you shared in the other thread
a couple of questions: 1. Did you or anyone in your team recently modified anything related to enroll secrets? do these hosts belong to a team? 2. Do you have access to the logs in any of the hosts? https://fleetdm.com/docs/using-fleet/orbit#troubleshooting
Hey @roberto Thanks for the help, No one has modified anything and no its not configured on teams basis. Also i updated the fleet from 4.21 to 4.26 and now everything is working fine so seems like it was some issue on fleet server side.
