Thanks for sharing the details
Your SSH session in VS Code is disconnecting because the server closes idle connections. Please follow the steps below to fix the issue:

1. Update the SSH server keep-alive settings:

Edit sshd_config and add:

ClientAliveInterval 60

ClientAliveCountMax 5

Then restart SSH and sudo systemctl restart sshd

2. Enable VS Code keep-alive:

Add this in VS Code settings "remote.SSH.keepalive": 30

3. Update your local SSH config:

ServerAliveInterval 60, ServerAliveCountMax , TCPKeepAlive yes

4. Ensure stable network/VPN connection.

These settings prevent idle-timeout disconnections and keep your VS Code Remote-SSH session active.
