    Hello,

    one of my customers is getting FTP issues which I can confirm lately. I'm not sure when it all started, but I also tried to upload files (folders, single files, zip archives, etc.) and everytime I'm getting a abort.

    From filezilla I'm getting this:

    Code (Text):
    Status:    Starting upload of MYARCHIVE.zip
    Status:    Retrieving directory listing of "/private"...
    Command:    TYPE I
    Response:    200 TYPE is now 8-bit binary
    Command:    PASV
    Response:    227 Entering Passive Mode (67,205,153,140,144,241)
    Command:    MLSD
    Response:    150 Accepted data connection

    Response:    226 4 matches total
    Command:    PASV

    Command:    REST 37404672
    Response:    350 Restarting at 37404672
    Command:    STOR MYARCHIVE.zip
    Response:    150 Accepted data connection
    Error:    File transfer aborted by user after transferring 74.474.333 bytes in 5 seconds
    Status:    Disconnected from server
    Error:    GnuTLS error -110 in gnutls_record_recv: The TLS connection was non-properly terminated.
    Status:    Server did not properly shut down TLS connection
    Error:    Could not read from socket: ECONNABORTED - Connection aborted
    Error:    Disconnected from server
    
    


    I have checked if the IPs are blocked with
    Code (Text):
    csf -g IP
    


    But none of the IPs are blocked from the people who try top upload. Right now I'm stuck and out of ideas on what to do :/

    Thanks for your help!

    I personally have tried it with Windows10 (Latest build, 2004 - 19041.546), tried with Filezilla and WinSCP.

    Customer tried it with latest MacOS with Filezilla and Cyberduck.

    Every tool is up2date.

    I dont see any port flooding.

    Concurrent is set to 1 max.

    I have also changed the auto-generated password since it contained special characters, but still no luck.

    EDIT: What I also noticed, when I upload a 100mb file the progress bar is going instant to 99%, then stops for around 3-4 seconds and then the error pops up.

    On WinSCP I get this error:

    Code (Text):
    Timeout detected. (control connection)
    Copying files to remote side failed.
    


    EDIT 2:

    The upload somewhat works, but its uploading it in phases (?), its aborting the connection, reconnecting, then uploads again. The full log of the upload:
