Zombie session after around one day: Live Share host is offline

[SichangHe]

After I open a Live Share session and leave it on for around one day, I cannot join it anymore although it seems to be alive on the host.

When joining via the link within VSCode, it first loads the session and then shows this popup:

Joining collaboration session: The Live Share host is currently offline. This usually occurs due to the host machine being in sleep mode or host connectivity issues. Please ask them to verify their session is active.

This is the popup when joining via the link in the browser:

Joining collaboration session: Unable to connect to the host. Verify both you and the host are online.

What was your system configuration?

• Client: VSCode 1.92.1 Darwin arm64
