fix #2632 - handle socket close in "socket initiator" phase

[leibale]

Description

fix #2632.

Until this fix, when the server closes the socket (for example, when the server is restarting) in the "socket initiator" phase (while running commands like AUTH, which has to run before all commands), the client hangs.
