In most cases, a small mistake while entering the server details to set up the connection is the problem. Here’s a small checklist to run through:
- Copy and paste the SFTP server details, especially the password, carefully. Sometimes you can accidentally copy a blank space as well.
- If you typed your password manually, make sure you spot the difference between ‘I’ (big i) ‘1’ (number 1) and ‘l’ (small L).
- In your FTP client, have you changed the transfer protocol to ‘SFTP/SSH File Transfer Protocol’? The default for most clients is ‘FTP/File Transfer Protocol’ only.
- The value for the port is missing or wrong. Maybe you forgot it; or it sometimes it switches automatically to another number. This is common, for example, when you switch the transfer protocol from FTP to SFTP: so go back and make sure the port number in your FTP client matches the one in the details we’ve supplied.
