Powershell - Can't connect to PSGallery

Hi everyone,

I am trying to get MicrosoftPowerBIMgmt from PSGallery and it returns an error. The code i have used is:

Set-PSRepository -Name "PSGallery" -InstallationPolicy Trusted
Install-Module -Name MicrosoftPowerBIMgmt

It returns an error "PowerShell Gallery is not available. Trying later". 

I have tried many days and the error is always the same.

Can anyone help me, please?

Thanks,
