Forge Tunnel on VMWare Ubuntu

HI
I am having trouble getting forge tunnel to work on Ubuntu 20 and 24 running on Win 10 VMware VM.

The tunnel run in verbose does not appear to show any problems and just waits while the app (a basic hello world issue glance) just spins on the issue page trying to contact my machine.

Same app tunneling works when I run from my mac and when I run on base win host.

Is there anything I should be looking for on the VM ware set up on WIn 10 that would stop the app contacting my VM?

Any help much appreciated.
