when using FTP this error occurs

is usually some service for FTP that’s not turned on and this has something to do with the firewall

if you are able to link to FTP but can’t see the file upload and download there is no way to do

then the command

can be executed

getsebool -a | grep ftp

will find the following states are closed

setsebool -P allow_ftpd_full_access on

setsebool -P ftp_home_dir on

execute the command above and return the result to see both lines are off, meaning, no access

you’ll notice that the state is already on

it should be no problem, if still won’t do, and see if it is to use the FTP client tool with the passive mode access, such as tip if passive mode, the means is passive mode, the default is no good, because of the passive mode FTP was held up by the iptables, here can speak how to open, if don’t open, just to see if your FTP client has the option of a port mode, or remove the passive mode options.
