I have been following the following for configuring an app domain in our SharePoint 2013 environment. When I reach the step for New-SPSubscriptionSettingsServiceApplicationProxy, I am getting the following error:
New-SPSubscriptionSettingsServiceApplicationProxy : A SPSubscriptionSettingsServiceApplicationProxy with id '4f0c42b1-5288-4057-8686-97464082df9b' already exists. Only one can exist per farm. At C:\Users\spfarm10\Desktop\Set_App_Domain.ps1:19 char:16 + $proxySubSvc = New-SPSubscriptionSettingsServiceApplicationProxy
What would be the best method for resolving this error?
