Issue/Introduction
Unable to connect to EM using Workstation Client.
There is the following message when connecting to the EM using the Workstation Client.
Sometimes a restart of APM allows temporarily reconnecting to the application. Also noticed that it doesn't disconnect an user who is already connected.
