Functioning Cluster Wont Talk to UI

[Bryan_Dobson]

Hello, I have a working Rancher cluster running 1.21.7 on Rancher 2.6.2 which shows active and is working insofar as I can tell but when looking at the list of clusters in dashboard/home it shows as being white and inaccessible to the UI.

I’ve checked the controller as best I know how and am not sure where to look. This happens from time to time and restarting the Rancher server itself sometimes brings it back but that is far from an ideal solution.

Any tips would be appreciated.

Problem solved.

I should have noticed but the issue was the time had drifted too far on the controller. When that happens it loses touch with the Rancher UI and likely numerous other things.
