    The ftp is working properly after recently code updates if I remember right.

    The following is logs (real ip is replaced):

    Well, I don't know.

    I pasted the logs here:ftp - Pastebin.com

    I wonder if there is a way maybe to recreate the ftp without touching the existing files? Or duplicate a new ftp user with the same permission and then delete this error one?

    tried updating to FlashFXP 5.4.0 ? Are you using CentOS 7.4 ? when did you update from CentOS 7.3 to 7.4 ? I see your logs trying to connect via SSLv3 which i think was deprecated in CentOS 7.4

[R] Connected. Negotiating SSL/TLS session

[R] Data Socket Error: Failed SSLv3 negotiation, disconnected


    tested with FlashFXP 5.4.0 on CentOS 7.4 based Centmin Mod
    Code (Text):
    [18:01:46] [R] MLSD

    You may need to change order of ssl ciphers used in FlashFXP

    Hmmmm, the ftp is now working fine, and I didn't modify anything. Very strange, just like it went wrong without any reason.

    For your reference, the VPS's CentOS is 6.9Final.

    Are logging in from multiple local pc/lan devices ? If so, see FAQ items 40 & 41 for details and clues.
