Cannot Deploy Process Server in Azure

I am probably missing a step but I cannot deploy an Azure Site Recovery Process server in Azure.

In Azure, I click 'Manage' - 'Site Recovery Infrastructure' - 'Configuration Servers' under 'For VMware & Physical Machines'.

I click on my On-Premise Configuration server and click '+Process Server'.

I select 'Deploy a failback process server in Azure'.

I choose subnet...and then it asks for server name. I enter Failback01.

I fill in the rest of the fields and click 'OK'.

I get a message "Initializing deployment....' and then about 3 seconds later, I get 'Deployment Validation Failed'.

Here is the exact error:

Deployment validation failed
Deployment validation failed.
Additional details from the underlying API that might be helpful: The template deployment 'AsrPsDeploy-FailBack01' is not valid according to the validation procedure. The tracking id is '4112ab79-ad91-4f33-a247-e5351e2d0bed'. See inner errors for details.

What I'm wondering is that the template deployment has prepended 'AsrPSDeploy-' before my server name. I'm guessing its trying to make a server with a name that is 22 characters which is impossible. Since the prepended name is 12 characters....I'm guessing my server name can only be 3 characters, but when I enter the server name...it has to be at least 5 characters.

Has anyone seen this? Is there a place where I can change the AsrPSDeploy- name to something shorter? I shouldn't have to load the PowerShell ARM modules..right?

Any help appreciated, especially if you have seen this.

Thanks,

Todd.
