Long Lived Tokens - VSCode on a second machine

I’m using the HA Config Helper on VSCode. I’m in the process of migrating to a new computer and so have synced the VSCode settings.

I can see the Long Lived Token (LLT) in the helper config on VSCode, but I am getting an error when trying to log in to use it.

Is this how LLTs are supposed to work or is it a different problem?
