Service Fabric Cluster Deploy Fails

I'm having a problem deploying a cluster to Azure. I'm using the template provided through Visual Studio (2017) as described here, securing it with a server/cluster certificate as described here.

I'm deploying via Visual Studio and the template seems to deploy successfully without any errors. However, when looking at the cluster in the portal it gets stuck in the "Deploying" state with no nodes appearing. RDP:ing into individual nodes and looking in the event viewer (Windows Logs/System) revelas that the Azure Service Fabric Node Bootstrap Agent service is stuck in loop, starting/stopping seemingly indefinitely.

Looking under Windows Logs/Application i can see the following (4) errors/warnings repeated for each restart attempt:

Restarting the nodes does not help and I have verified that that the certificate gets installed on the VMs. I'm getting no errors logged in the portal, just the "Deploying" message on the cluster. Nodes are Windows Server R2. Any ideas? Obviously the path given to System.IO.Path.GetFullPathInternal is null but what could cause that?

Maybe this is the right answer: http://amolenk.com/2017/03/15/ServiceFabricNodeBootstrapAgent-breaking-change/
