Hello.
Till last year it was possible to use UltraVNC successfully with the Intel vPro KVM feature (RFB password via Port 5900).
It seems that Intel has disabled support for this access method for security reasons and so we can no longer use UltraVNC for that.

https://github.com/Ylianst/MeshCommander/issues/98
As it is still possible to access Intel KVM via MeshCommander I wanted to ask if there is still a way to use UltraVNC with updated Intel Firmware?
Seems that this user has developed a VNC shim layer in Python to make it still work

Thanks

Support for Intel vPro KVM
Re: Support for Intel vPro KVM
Some additional notes:
New Intel firmware only disables non-TLS port 5900 for VNC. TLS connections over port 16993 and 16995 still work.
What the smart guy writing the shim layer did to make it still work is the following:

As Intel also abandoned the software MeshCommander to force their customers to use their cloud management software it would be a real USP if UltraVNC could still be used for Intel KVM.If you want, you can create a VNC shim layer to allow VNC client like Tiger VNC to talk to AMT KVM. This shim layer basically handles AMT Websocket Digest Authentication and initial KVM negotiation before shuffling the RFB3.8 stream between AMT and VNC Viewer.
