Dynamo Player not working with Zscaler proxy

We are having trouble getting Dynamo Player to work with Zscaler. It seems to be routing localhost:xxxx requests to Zscaler while it should stay local.

Does anyone understand how Dynamo Player work? Does it use WebRTC locally? I remember seeing something about WebRTC in this KB page but it’s been modified and removed since Aug 23 - Unable to launch Dynamo Player in Revit | Revit | Autodesk Knowledge Network


Maybe here: (haven’t checked)
