Cause : Timeout setting incorrect in FTP software or Packet loss in network
The problem is related to the internal timeout settings of FileZilla. Actually there is a predefined timeout settings by default in FileZilla. So if your file is relatively large in size or your internet connection speed is not up to the mark, then the uploading process fails within that predefined timeout settings and this type of Connection Timeout error occurs and uploading starts again. For solution to this issue, you just have to configure timeout settings in Filezilla.
The steps to change the settings according to your needs are given below:
Step 1: Open FileZilla client application on your desktop. A new window will open for FileZilla.
Step 2: Then click Edit on menu bar and select Settings option.
Step 3: Then click Settings and a new small Settings window will open.
On the left side of the Settings window there is a subsection called Select page, select the top option called Connection (by default it is selected when you open Settings window, if it is not, then select it manually). When you click on the connection link you will get an option to set timeout on the right side. In that Timeout section you will get an option to set timeout value from 0-599 seconds. Set this according to your need or you can disable this Timeout settings by setting its value to 0.
Step 4: Now click OK.
For checking packet loss in network, ping your FTP hostname and check atleast for 500 packets.
C:\>ping ftphost -t
