You need to disable an option (UsePrivilegeSeparation) in the sshd_conf. This is a known issu (duplicate) related to un-implemented functionality. Please use the search interface in the issue tracker.

it‘s no use for me to disable UsePrivilegeSeparation. it still can't start.

i tried #614 (comment) also fail.

Did you also switch off port 22?

[hyec]

i tried other ports, also useless.
dropbear shows the same wrong info

I uncomment ListenAddress 0.0.0.0 to make it bind to ipv4 address only, than it works.
but i have ipv6 address, why it doesn't work ?
