Yeah So apparently Updating from V4.1.0.jar to V4.1.1.jar On Fabric 1.16.5 = Bad News .
1.16.5 Fabric Loader 0.13.3 is the last version Before, 0.14.0 which Disables/Guts out the Online Mode Features.

Hopefully in iknowwhatimdoing V4.1.2 there will be Support to Run/Operate on Fabric Loader 0.13.3.
