I am trying to install OpenSSH on a Windows Server 2019 machine in an environment without external network access and with a configured proxy at "". I am using PowerShell with administrative privileges and have set the HTTP_PROXY and HTTPS_PROXY environment variables as follows:
$Proxy = ""
$ENV:HTTP_PROXY=$proxy
$ENV:HTTPS_PROXY=$proxy
However, when I try to install OpenSSH using the following command:
Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0
I receive the following error:
Add-WindowsCapability : Add-WindowsCapability failed. Error code = 0x800f0954 At line:1 char:1 + Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Add-WindowsCapability], COMException + FullyQualifiedErrorId : Microsoft.Dism.Commands.AddWindowsCapabilityCommand
Other Invoke-WebRequests I am making seem to have proxy access, but the Add-WindowsCapability command is not working. I am unable to resolve this issue.

Add-WindowsCapabilityagain, it should be fixed
I want to share my solution. I searched a lot to solve this issue, because I wanted to solve this without changing the Group Policy's and wanted to use the CAB file as Source.
I used the following command:
Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0 -Source {path to the cab file} -LimitAccess
Every time I got an error. But then I looked at the logfile:
C:\Windows\Logs\CBS\cbs.log and realized that I used the wrong version of the CAB file. In the log file you can also see the expected version.
After downloading the right version, everything worked as expected!
