Hello
I am trying to connect to a cloud connected DMA remotely using the cube, and I am getting the following error "APIGateway is unavailable.". What's the best course of action?
DMA cluster is running on 10.4-CU2.
Thanks. 
By browsing to <dms>-<organization>.on.dataminer.services/APIGateway/ you can test/see that APIGateway is not reachable, otherwise it would say “APIGateway is running”.
In this case make sure that te APIGateway service is running in Services.

As one of the DMAs is in DMZ, your instructions to enable the HTTPS in DMZ CloudGateway resolved the issue.
In the appsettings file of the cloudgateway on the DMZ (C:Program FilesSkyline CommunicationsDataMiner CloudGateway) we have updated to enable HTTPS ( “IsHttpsEnabled”: true) in custom appsettings file of DMZ settings:
“DmzOptions”: {
“IsHttpsEnabled”: false,
“Domain”: null,
“DataMinerAgentName”: null
}
Then we restarted the cloudgateway service. We are now able to reach the DMA over the cloud connection.
I experienced the same problem. Found out that this extra step had to be done in my case – copying the “Auto-Created Certificate by DataMiner APIGateway” certificate from Personal certificate folder to the Trusted Root Certification Authorities folder.
The ones of you who already have certificates properly managed do not most likely cross this, but that was not the case for my lab system.
DataMiner APIGateway service is running.
