@Jagan1, do you confirm working behind a proxy?

If so, you have to set NODE_EXTRA_CA_CERTS environment variable (system wide) to reference your corporate CA bundle file.

@Jagan1
Please let's skip this quick pick and focus on the red text field. Has any device completion appeared when you start typing STM32...?
If not, could you please try running the following command in the VSCode integrated terminal:

cube pack sync

Does the process complete successfully? If not, please share the trace.

    Better to confirm this before going one way or the other.

    Could you paste the following line into your PowerShell terminal integrated in VSCode ?

    It should print the certificate information you see from developer.st.com domain.

    $cert = [System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
$tcp = New-Object Net.Sockets.TcpClient('developer.st.com', 443)
$ssl = New-Object Net.Security.SslStream($tcp.GetStream(), $false, ({$true}))
$ssl.AuthenticateAsClient('developer.st.com')
$ssl.RemoteCertificate | Format-List *

    Then past the output here.

      Handle : Number
      Issuer : CN="zscaler.xxxxxx.com (t) ", OU=Security Operations, O=xxxxxx Technologies, S=Location, L=Location, C=US

        No this is already good enough to highlight the fact that your behind a proxy doing SSL inspection.

        Then NODE_EXTRA_CA_CERTS is required to point to your Zscaler root CA certificates.

        If you can navigate to https://developer.st.com/ without troubles it likely means that such certificates are already trusted into your Windows certificate manager.

        You could try export them (Zscaler*) in base-64 encoded X.509 format, and gather all exported files into a .crt file respecting this kind of format:

        -----BEGIN CERTIFICATE-----
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-----END CERTIFICATE-----

        Then reference this file with NODE_EXTRA_CA_CERTS

        Ok, it is denied but at least you have the lock meaning connection is secured, so you can proceed with the rest of my previous message.

        AFAIR there should be at least 2 certificates, the Zscaler Root CA and the Zscaler Intermediate Root CA, as shown in this screenshot (again picked on the Internet):

        only one is there.

         I wonder from where you get this screenshot. If from the Windows cert manager then I think it is expected since you only view the selected certificate. But if you get the certificate by clicking on the lock from a browser you may get more certificates in the chain.
