The documentation provides these reasons for why VMs may show as Unsupported:
- Missing network security group (NSG) or Azure Firewall - JIT requires an NSG to be configured or a Firewall configuration (or both)
- Classic VM - JIT supports VMs that are deployed through Azure Resource Manager. Learn more about classic vs Azure Resource Manager deployment models.
- Other - The JIT solution is disabled in the security policy of the subscription or the resource group.
Please check to make sure none of these reasons apply to the VM. If you are unable to see the cause please let me know and we can work with you directly to resolve the issue.
