Virtual Lab not starting?

[john.aubrey]

Hello,
I have a strange issue. I have a virtual lab that has worked pretty well for months. When I run a surebackup job with it, it fails at the starting proxy appliance VM. I checked, and it actually starts up just fine, and when the job fails, it can turn it off just fine. This is on a Hyper-V cluster if that matters. I tried creating a new Virtual Lab on the standalone Hyper-V Host we have and same issue. I thought I'd reach out here before opening a ticket. I feel like I'm missing something stupid.

Can you reach the proxy via network from the Veeam server? I believe Veeam checks the network connectivity and determines if the proxy is running or not.

What that be my masquerade Ip or appliance IP?
