Click “Ok” to close the Filezilla settings popup.
Now go to the Filezilla Site Manager by clicking on the icon under “File” in the top tool bar. enter the IP address of your server where it asks for a host. Select SFTP for protocol. Select Normal as the logon type. Enter ec2-user as the user name and leave the password blank. Finally click connect to open your server and place a check beside the box to always trust…. so you don’t have to do it each time.
