iDRAC keyboard not working

Ok, no flames please as this question has been asked a million times. I simply cant get my iDRAC keyboard to work no matter what I try. I have googled till I am blue in the face and tried it all. I have an older PowerEdge T420 with iDRAC 7 Enterprise. I have updated to the latest iDRAC firmware (dated 2/2020) and LifeCycle controller. I am running the server as an ESXi Host using ESXi 6.7. The console opens just fine, but the keyboard simply does not work. I have tried, Chrome, FireFox and IE(yuk). No joy on any of them. I have tried Native, Java and HTML5, nothing works. I have even tried using a 32 bit browser on XP, still no joy. I have also tried both Windows and Linux browsers, and nothing works.  I cant help but feel it is something real stupid on my part as there is no reason I can think of why this should not work. I even tried disconnecting the physical keyboard as a list ditch effort, still no joy.

So, I then tried my MacBook, and finally got something I can use as an error. This error appears to be coming from Java : "The native library for keyboard and mouse support failed to load. To pass all keystrokes to the managed system, the virtual console application requires direct access to your keyboard. You can enable this in System Preferences/Universal Access and select Enable access for assistive devices option."

The only problem here is that the location this error mentions does not exist on my system. I tried Native, Java and HTML5 on the MacBook, same results as windows and Linux, no keyboard. Even if I bring up the on screen keyboard, it also does not work.

Can someone please point me to the error of my ways? Thanks in advance for any and all help.
