NOW-EDGE-INSTANCE_IS_UPGRADING NOW-EDGE-INSTANCE_IS_UPGRADINGSeverityCRITICALRoot CauseA scheduled upgrade was attempted while the (glide) instance was being upgradedEffectThe upgrade will fail during the HealthCheck stage. While the instance is being upgraded, edge proxies are not able to restart and authenticate with the instance. This make it impossible to complete an upgrade, as a restart of the new proxy version is required. This is why the HealthCheck will throw this error.Corrective ActionThe upgrade for this proxy can be scheduled for a later time, when the (glide) instance is not upgrading.
