Why does my SFTP account say "Authentication rejected by the SSH server"?
Short answer: The server rejected the sign-in. Check the username (case-sensitive), the current password, whether the server only accepts keys, and whether it restricts which users can sign in.
The server is reachable but won't accept the sign-in. Check:
- Username — it's case-sensitive.
- Password — make sure it's current and copied correctly, especially if it contains symbols.
- Sign-in method — some servers only allow key-based sign-in; if so, switch the account to a private key.
- Server rules — the server may only allow certain users.
A quick test is to sign in with the same details from Terminal or another SFTP app; if that works too, edit the account and re-enter the details.
