Can't connect using Filezilla

Until now I had no problem connecting to the cloud since today. I accidentally cancel a file downloaded and exit Filezilla.
Then I got this error whenever try to connect.
I think that the error is due to this “fzsftp started, protocol_version=8”
I increased timeout but nothing.
Has anybody any solution that fixes this, I found on www some answers such as to put filezilla.exe and fzsftp.exe in firewall white list but does not work.
Or suggesting any more reliable sftp client for windows?

Response: fzSftp started, protocol_version=8
Command: open “customer@142.xx.xxx.xxx” 22
Error: Network error: Connection timed out

Looking into this via email.
