why can't I ftp

I have been able to use ftp for a couple years for my bplaced website kalugames.bplaced.net. But suddenly it does not work any more. Since it seemed to suddenly not recognize my password, I changed it, but it doesn’t recognize the new either.
TLS connection established.
Command: USER kalugames
Response: 331 Hello kalugames, your FTP account password is required:
Command: PASS *************
Response: 530 Login authentication failed
Error: Critical error: Could not connect to server

How have you changed your password?
