VS Code report: "Unable to contact the STM32Cube registry, verify your Internet connection..."

Hi @emiya0306
If you are hidden behind your company security, you probably need to configure a proxy and certificate to be able to access servers and download packages

How to Configure the proxy:
Put your proxy in this format http://user:pass@Proxy-address:port
How to Configure the certificate:

Hi @emiya0306,
There is an error in the output shown in one of your screenshot, but partially visible because of vscode notifications.
Could you open a vscode terminal, execute the command cube bundle list-online, and paste here the error if any ?

Then next commands fail because of that. For sample the pack command is missing because it is part of pack-manager bundle.
Can you open a VSCode Terminal and enter cube bundle list-online command to see if output is more verbose ?
Here is what you are supposed to get:

This is not expected at all, let me check that with the Team and I’ll get back to you.
We might need further details on your setup, like country location for example.

Could you give a try to another similar command enabling more verbosity and listing all platforms/architectures bundles: cube --verbose bundle list-all-online
