FTP upload is frequently interrupted
First, confirm whether the ftp client of your local computer is in active mode (Port) or passive mode (PASV).
If the ftp client of the local computer is in active mode, you need to confirm that you have opened high-end ports on the server and specified these ports in the FTP server.
If the ftp client of the local computer uses the passive mode, you need to open the relevant ports locally for data interaction (you can turn off the local firewall). However, if your network structure is limited (such as firewall, routing restrictions), it may cause normal use failure and frequent connection interruption.
If the above problem is eliminated, please confirm whether your local network environment is stable and your server bandwidth is full;
If the above problem is eliminated, please confirm that the "Data Transmission Timeout" setting on the ftp server side (that is, on the server) is large enough: for example, when using vsftp on Linux, you need to modify it /etc/vsftpd/vsftpd.conf In the file data_connection_timeout Parameters.
The operation in Windows system is complicated. Please refer to this link: http://www.iis.net/configreference/system.applicationhost/sites/sitedefaults/ftpserver/connections 。
If the timeout setting is large enough, you can test the local network first. If the problem of the local network is eliminated, you need to submit a work order to contact the technician, and upload various outputs and results of the test local network to the work order.
