PreStage Enrollment Mac Activation - Request timed out

New Contributor



When trying to activate a new Mac that was added to the PreStage Enrollment we get the following error : 

Mac Activation - The request timed out. 

Which ports needs to be opened in order to activate Mac for PreStage Enrollment on our Proxy?

Would it be the as mentioned in this article?


Any help would be appreciated.


Thank you!
