Troubleshooting deployment issue

I’m trying to deploy a Linux virtual machine, using AzureRM_Linux_Virtual_Machine. I used this exact same code to successfully deploy a VM on Friday, but today it just sits at creating for 20+ minutes before I kill it to try again. The connection to Azure seems fine, I’m using remote state stored there and I’ve deleted a few resources this morning before this. What logging/debugging can I use to try to figure out what is going on?

Thanks,
Andrew
