Plesk Automation :: Setting Up CloudFlare On Out PPA System

I am having issues setting up CloudFlare on out PPA system. I have is setup under Hosted Applications. I have setup a Resource for CloudClare and added it to the service templates. When i go into a clients Control Panel to install the app, I get a couple different errors. When i try to use a previously setup administrator for the subscription, which is listed under "Grant administrative access to existing user," I get the following error:

"Error: Installation of CloudFlare For PA failed. invalid values passed for settings of application resource; details for setting with id 'admin_username': The "CloudFlare username" setting value 'xxxxx' is already in use. Please provide unique value." Is this because I am logged in as the user?

When I create a login under "Use administrative credentials not connected to any particular user," I get the following error: "Error: Installation of CloudFlare For PA failed. Invalid structured output returned by script: Failed to parse structured output. Structured output: '<output xmlns= URL.... WARNING: A connectivity error occurred while contacting the service. WARNING: A connectivity error occurred while contacting the service. WARNING: A connectivity error occurred while contacting the service. WARNING: A connectivity error occurred while contacting the service.'. "

I do get an email from CoudFlare with the setup instructions for the new account.Under the PPA control panel, I am using the IP address for the Management Node in the "POA API IP" field. Is this correct, or should I have entered localhost?I am running 11.5 Update 8, and CloudFlare For PA (3.0.2-18).Setup instructions for Plesk or POA does not quite cover everything for a PPA installation.
