PowerBI Powershell and API Upload 401

We are on the USGov environment for our PowerBI. I am receiving 401 Unauthorized errors using the PowerShell MicrosoftPowerBGMgmt cmlets, as well as when I invoke the PowerBI rest api attempting to upload .pbix files. This is given to me in my own workspace. Has anyone else experienced this problem and found a work around? Is this possibly because it is in the USGov Environment? I am not restricted in anything else. I can delete, export, etc. on everything. Have tested in both my workspace and organizations workspaces. Any help would be greatly appreciated.
