About the Error
This error occurs when a remote File Transfer Protocol site is not accepting your log in. The error message could also read as “Log in authentication failed” or “Password rejected.” This indicates that the host address (URL), your username or password is wrong and the site’s security set up is rejecting it.

Check to see if the URL, username and password are correctly entered. If you are using a Password Manager, check to see if the data you have saved has become corrupted in any way. Keep in mind that the details for each website are different and you may have set up different authentication information for a specific site. If the information you are sending is okay, there is no need to do anything else with your computer as the fault lies with the FTP server. If, after ensuring that the information you are submitting is correct, the problem persists, it may be a technical glitch with the FTP server. Servers are prone to both hardware and software problems such as data corruption or virus infection. Wait a while so that the site administrators have time to rectify the problem and try again. It is also possible that your username or password has been changed or derecognized for some reason – possibly because of a virus that has entered the server. If giving time to correct itself does not result in your being able to access the site, contact the site administrator with details of the error message received. The Administrator’s contact details are usually given at the bottom of the site’s home page. Alternatively, you could try the resources available on the Help and Contact Us pages of the site. As a short term fix you could try setting up a new account –this will give you access to the site but records of previous actions will not be available.
