Error with PowerShell cmdlets

Question

Folks,
I've recently started getting errors in PowerShell e.g. "WARNING: MSG:UnableToDownload «https://go.microsoft.com/fwlink/?LinkID=627338&clcid=0x409» «»" and "WARNING: Unable to download the list of available providers. Check your internet connection."

I can run the TLS fix I found on another forum but it is not persistent. Any ideas?

Lisa.

Hello @LisaLownds-9214,

TLS fix you mentioned is a workaround for the issue. You may follow the steps below for a permanent solution by a registry value adjustment

1. Open Powershell and check for supported protocols by using[Net.ServicePointManager]::SecurityProtocol
2. Run the following 2 cmdlets to set .NET Framework strong cryptography registry keys:

Set strong cryptography on 64 bit .Net Framework (version 4 and above)

 Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

set strong cryptography on 32 bit .Net Framework (version 4 and above)

 Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

Restart Powershell and check again for supported protocol by using [Net.ServicePointManager]::SecurityProtocol

Please mark as "Accept the answer" if the above steps helps you. Others with similar issues can also follow the solution as per your suggestion

@ManuPhilip thanks. I read that in the article when I found the fix. However, I am now curious to know why I need to do this and what has changed?
