    SFTP Error code is 96258

    Dear Users,

    Regarding the SFTP-Error: “Connect Exception Error Wrong socket state 4 in AsyncConnect (error code is 96258)”

    The feedback from we got from our SFTP Source code provider is the following:

    1) Restrict your SFTP security options and try again

    2) Enable Suppress Additional Operations (due to some buggy SFTP servers) and try again

    More information:

    SFTP connection to the server is not established. WTF?
