Multiplexed Connections Rejected with 'Shared Connection Closed'

[heiytor]

Description

Description

ShellHub is rejecting connections when the client is configured to use multiplexed connections.

Steps to Reproduce

1. Enable multiplexed connections.
2. Authenticate to a device.
3. Attempt to reauthenticate to the same device with the previous connection still open.

Note: Connections using -f will succeed in connecting the next attempt, but subsequent connections attempts will fail.

Expected Behavior

The client should reuse the existing "master" connection, bypassing, for example, the authentication step.

Actual Behavior

The server rejects subsequent connections with a Shared connection to localhost closed. error.
