Anyone else experienced an issue using the DataMiner Virtual Hard Disk - DataMiner Dojo as a baseline and then upgrading to DataMiner Main Release 10.6.0.0 – 16833 CU0 - DataMiner Dojo breaks Cloud Gateway? Is there an easy workaround? From what I can see the process runs fine, I see I lost my cloud connection generally speaking via cube/systen center and if I try to connect it complains its not running but it is from a process standpoint in the OS. Logs for SLDataGateway seem to spam the same error repeatedly...

During the upgrade, the CloudGateway got shut down to upgrade, which caused the spam of errors which is a race condition but not really a problem. It then failed to start up during the dataminer upgrade which made it seem offline while it was infact running.

The state of being cloud connected is also retrieved from the CloudGateway DxM and if this isn't running it defaults to not connected.

With 10.5CU9 base upgraded to 10.6 breaks Cloud Gateway
