Command: Pass: *********** Error: Connection timed out after 20 seconds of inactivity Error: Could not connect to server code example

Example: filezilla 20 seconds inactivity

In my case

Click Edit on Menu
Click Settings
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.
