Host is not communicating for more than 15 seconds....
Hello,
we have an SFTP server and we use WinSCP as client, it was working fine since these days, I'm always getting this error "Host is not communicating for more than 15 seconds" then it abort connection, and the speed in very slow.
I tried to disable optimise connection buffer and increase time more than 15 seconds.
I tried many version of WinSCP but same problem. Please help.
