The ping page (http://localhost:3000/ping) will work and show that all of the microservices are functioning properly but Active Workspace will not respond. When entering http://localhost:3000 it will give no response.
Solution
The gateway.log contained "Unexpected header from filerepo: x-oneagent-js-injection = true, true"
This was caused by Dynatrace being enabled on the system to track activity and injecting tracking info into the header of the packets. The Ping page is unaffected by these but they do cause Active Workspace to fail.
There is nothing that can be done from the Active Workspace side to accept the extra header information. There will need to be some adjustments on the Dynatrace side to white list or ignore the Active Workspace communication.
