Email Client Information not available
I am following the online course : Pega Customer Service Essentials (8.x) .
In module 3 I need to open the Email Client Information to test a common phrase I added. However, when clicking the link (http://env-1819786234.pegaenablement.com:8100/) I receive the following error "Site is not available. It takes to long for env-1819786234.pegaenablement.com to respond" (freely translated from Dutch).
