Last night the cluster was working properly, but this morning the cluster was terminated automatically and cannot be restarted. Got an error message under sparkUI: Could not find data to load UI for driver 5526297689623955253 in cluster 1125-062259-i70yabdd

In compute there is a run icon to restart but this one also doesn't work. Got an error saying Cluster Start feature is currently disabled.

Anyone has an idea about how can I restart the cluster?
