Optimize buffer size in WinSCP

Question

Actually, When ever I opened my WinSCP, it is showing

Host is not communicating for more than 15 seconds and turn off optimize connection buffer size

Please help some this please give some ideas ...

Thank you.

Solution

WinSCP documentation for error message Host is not communicating for more than 15 seconds says (among other):

If the problem repeats, try turning off Optimize connection buffer size.

(actually there's "Help" button on the error message box, which gets you to that page)
