Hi.
So late reply, but one of cause and solution that

  1. When IPv6 setting on in the setting > system > network > [wifi or ethernet],
    some of process bind and listen at port 3456.
    So disable the IPv6 of Wifi and ethernet

  2. if this not works,
    go into the ssh, do whatever with linux commands to identify process which holding the port 3456 and kill yourself. like (# netstat -l | grep 3456, and so on so on.)
    For the ssh, easy way,
    install below and turn off ‘protect mode’ at the config page.
