FTP 530 Login incorrect

How to fix FTP 530 errors: bad credentials, account restrictions, FTPS requirements, and permission issues.

FTP code 530 is an authentication failure. The server rejected the username/password or refused the account.

Common causes

  • Wrong username/password
  • Account disabled or locked
  • Server requires FTPS (or disallows plain FTP)
  • IP allowlist / geo restrictions on the account

Fixes to try

  1. Confirm credentials with the server owner (copy/paste to avoid whitespace).
  2. Confirm whether the server requires FTPS (explicit) instead of FTP.
  3. Check whether the account is restricted by IP allowlist.
  4. Try a known-good FTP client from the same network to compare behavior.
