There are several common software solutions for socket errors in FTP

Now everyone logs into our FTP server and will encounter a socket error. Everyone uses different FTP software, so today I will tell you several solutions to the commonly used FTP software.

Cute FTP 3.5 English version: FTP—> SetTIngs—> OpTIons—> Firewall, remove the tick from the check box in front of “PASV mode”

Cute FTP3.5 Chinese version: FTP—> Settings—> Options—> Firewall, remove the tick from the check box in front of “PASV method (A)”.

Cute FTP4.0 Chinese version: right-click on the ftp site you created —> select properties (properTIes) —> remove the "use PASV mod" option

Cute FTP Pro2.0 Chinese version: Edit—> Global Settings—> Connection—> Connection Type, select “PORT” from the “PASV / PORT” drop-down menu.

Leap FTP2.7.2: Sites—> Site Manager—> Advanced, remove the check mark from the check box in front of “Use PASV mode”.

flashfxp: Options-> Parameters-> Proxy-> Remove "Use Passive Mode"

The cause of such problems is generally caused by the conflict between the client network exit and the server firewall port settings.
So for other software, as long as you do not choose PASV as the connection type, you can generally solve this type of problem.
