Not capable of connecting a Logitech MX Keys to UNRAID Server

I am using a Startech BT dongle based on Realtek - RTL8761B chipset and have already installed bluez.5.71 (using NerdTools plugin)

I have followed these instructions:

I am capable via command line to: (1) scan, (2) pair (after typing a passcode provided on the screen) , (3) trust, (4) connect, but no return (echo on the screen) after all these steps. 

This came from syslog:
