I have created a new ec2 instance and installed ftop on it i can able to access it through putty and winscp suddenly, once when i try to open through winscp it is giving error as
The server rejected SFTP connection, but it listens for FTP connections. Did you want to use FTP protocol instead of SFTP? Prefer using encryption.
and through putty it is showing as CONNECTION REFUSED i even tried restarting the instance may i know what is the problem it is very important for me kindly help.
