Logs

[warn] Could not fetch kernels from the remote server, falling back to cache: Error: request to https://jupyterhub.xxx/hub/api/authorizations/token failed, reason: unable to verify the first certificate

I added the certificate to the OS CA, but it didn't help

We are experiencing similar behavior from a Windows client.

10:10:59.448 [error] Error sending request to https://hostname.example.com/hub/api FetchError: request to https://hostname.example.com/hub/api failed, reason: unable to verify the first certificate

    > type = system
    > errno = UNABLE_TO_VERIFY_LEAF_SIGNATURE
    > code = UNABLE_TO_VERIFY_LEAF_SIGNATURE

Interestingly connecting to JupyterHub from a MacOS client works fine.

On the Windows client I have the following settings set based on other related suggestions found in this repos issue tracker:

"jupyter.allowUnauthorizedRemoteConnection": true,
"http.systemCertificates": true,
"http.experimental.systemCertificatesV2": true,
"http.proxyStrictSSL": true,
"http.proxySupport": "override",

We experience the same behavior from both the Pre-Release and Release versions of the extension.

Release Version: v2023.10.1003012305
PreRelease Version: v2024.5.1002140811

Our company certificates are installed on both the client machines (MacOS and Windows). Any help on this issue would be greatly appreciated!
