What happened?

I have a remote jupter server set up. It's hosted on vast.ai which configures everything for you.

I should be able to conect to it with https://185.65.93.114:42131/?token=<TOKEN_STRING>

However, this fails with "unable to verify the first certificate"

The problem is that jupyter uses a self-signed certificate.

Enabling setting jupyter.allowUnauthorizedRemoteConnection is meant to fix this (e.g. https://github.com/microsoft/vscode-jupyter/issues/7558). However, it doesn't seem to make a difference.

I confirmed that setting env variable NODE_TLS_REJECT_UNAUTHORIZED=0 and restarting does fix the issue. But this is a cosiderable pain compared with a user setting.
