In my case

1. Click Edit on Menu
2. Click Settings
3. Set Time Out to '0'

That's it. It worked in my case. Tried all the above mentioned methods but it wont make any change in my problem.

By just disabling the time out it worked.

1. Open FileZilla client application on your desktop. A new window will open for FileZilla.

2. Click Edit on menu bar and select Settings option.

3. Click Settings and a new small Settings window will open. In 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 settings its value to 0.

I had the same problem when I switched from a D-Link router to a Asus RT-AC68U.

My problems where solved by disabling the NAT Acceleration. This description is for a Asus router but look for NAT Acceleration/Hardware acceleration or something like that, if you have another router.

1. Login to the router
2. In the left menu, under Advanced Settings, click the LAN button.
3. Then click the Switch Control tab.
4. Set NAT Acceleration to Disable.
