some Powershell commands not all working

 Ran into a problem when running some powershell commands, these were specifically for Microsoft Teams

I kept getting errors running this command

Get-CsOnlineTelephoneNumber -TelephoneNumber 15552129191

Get-CsOnlineSession : Connecting to remote server api.interfaces.records.teams.microsoft.com failed with the following error message : The WinRM client cannot process the request. Basic authentication is currently disabled in the client configuration. Change the client

configuration and try the request again. For more information, see the about_Remote_Troubleshooting Help topic.

My coworker told me they had same problem and had to change a registry entry

DWORD "AllowBasic" = 1

Was able to run successful commands that were failing prior
