Server 2022 Preview missing Let's Encrypt Root certificate

Copper Contributor

First posted to and was advised to post this issue here.


At the time I'm writing this, Microsoft Windows Server 2022 has not been released and is only available in "Preview". Having said that I've installed the "Preview", installed all patches, and experienced the following errors when connecting to resources that use LE certificate. This happened when using Edge and Chrome.


Your connection isn't private
Attackers might be trying to steal your information from (for example, passwords, messages, or credit cards).



Firefox worked fine since it uses its own certificate store.


After adding the root certificate to the root store, all was fine.


The following output shows the certs currently in the root store by default as well as the PowerShell & OS version:




PS C:\> gci Cert:\LocalMachine\Root

@petercooperjr in the previously mentioned Let's Encrypt thread offered this feedback.


Thanks. I don't know if it'd help whomever looks at it, but if you look at the Microsoft Trusted Root Program's page of their current trusted roots, you can see that ISRG Root X1 is there. (And it looks like ISRG Root X2 is there too!) phbits_0-1628221444675.png

Please verify the following:

1. Open Services.msc and verify that the "Cryptographic Services" state is Running.
2. Run Windows Update. (Windows Cryptographic Services is responsible for downloading the root certificate from Windows Update once that chain is needed)

The system has all security updates installed.

Confirmed that CryptSvc is running with `StartType=Automatic`.

Restarted the service: `Restart-Service -Name CryptSvc`

Checked Windows Update to find no new updates.
