I was running a command to install a PowerShell module, e.g.
Install-Module -Name navcontainerhelper -Force
while I received the following error message:
Unable to resolve package source ‘https://www.powershellgallery.com/api/v2’
Run PowerShell as Administrator and run the following command to force to use TLS1.2 protocol
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
