Subscription Issue

Hello.

I am having an issue with the subscription function.  Anytime I attempt to subscribe to a report receive the following error:

I have checked to role permissions, ROOT URL, and I'm not sure what is causing the error. 

The RSPortal log did return the following: 
2024-06-06 10:04:26.3373|ERROR|54|OData exception occurred: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Net.WebException: The remote name could not be resolved: 'n'
