VSCode in disconnected environment pops-up an Error loading webview

[jstourac]

What steps did you take and what happened:
I started the latest build of the VSCode server in a cluster in disconnected environment via JupyterHub spawner. Once I navigated into the VSCode IDE UI in my browser, I can see an error as a pop-up message in lower right corner and available also in the IDE output window:

[error] [Service Worker] registration Failed to register a ServiceWorker for scope ('https://jupyter-nb-***-rhods-notebooks.apps.***.com/vscode/') with script ('https://jupyter-nb-***-rhods-notebooks.apps.***.com/vscode/_static/out/browser/serviceWorker.js'): An SSL certificate error occurred when fetching the script.

(the *** is shortened text)

What did you expect to happen:
No error message shown in the UI
