It looks like the Ping MP isn’t reporting configured hosts that are down.
If you configure a server that must be monitored by the Ping MP (called Target Host) you specify an IP address using the Configuration Dashboard. If you don’t specify a valid IP range, for example an extra space / other chars or 255+ numbers, the workflows will be unloaded by SCOM. This will result in a ‘false positive’ situation. You think the servers are pingable because SCOM reports a healthy situation, but it could be they aren’t. The Operations Manager NT Eventlog of the configured Ping Host (the SCOM agent you use to execute the ping checks for the target hosts) will contain 1206 events, describing the unloading of the workflows.
Please check if you have entered valid V4 IP ranges. So no chars (example: trailing, leading spaces) and numbers higher than 255. If you have a big list of configured ping servers you can use the Export/Import Batch function found in the OpsLogix Ping IMP configuration dashboard or you can press CTRL + A in the Targets -> Status View and copy the section to an excel sheet. Review the IPs and fix the incorrect ones.
