Winscp disconnect all the time

Hi, Winscp disconnect all the time when I'm inactive for 2 or 3 minutes, and then when I save a file need wait 15 secs then appears error message and reconnect, is so frustrating. I have the same configuration in office and don't happen, it's my network? some problem with ports?? can u help me?

WinSCP does not disconnect on its own. It's rather getting disconnected by a network or the server.

Did you try to turn on keepalives?

hello, thanks for u reply,

What option i should put?
sending null ssh packets or execute dummy protocols commands?

Thanks

Whichever works for your server. Try both.
