Introduction

Sometimes the FTP user name, password and host look correct, but the connection still fails.

In that situation, the problem is often related to the port, the client configuration, the firewall or an IP restriction rather than the login details themselves.

Steps to troubleshoot FTP access

  1. Confirm the exact host value.
  2. Recheck the FTP user name and password.
  3. Make sure you are using the correct port, usually 21.
  4. Confirm the client is using the expected protocol.
  5. Test from another network if possible.
  6. Check whether your IP may have been blocked after repeated failed attempts.

Useful tips

  • Copy and paste credentials carefully to avoid hidden typos.
  • Test with another FTP client to rule out a local configuration issue.
  • Try with the server IP if the domain is still propagating.
  • Review local firewall or antivirus rules.

Frequently asked questions

Why can I not connect if the password is correct?

Because the failure may be caused by a blocked IP, closed port, wrong host or incorrect protocol.

Which port does FTP use?

The standard FTP port is usually 21, although secure alternatives may use other settings depending on the service.

When should I contact support?

If you have already checked the credentials, tried another network and reviewed the port and host, support can help confirm whether there is a block or server-side restriction.

Conclusion

If FTP still fails even with the correct details, review the whole connection path: host, port, protocol, firewall and IP status. Most FTP problems are solved there.
