I was unable to connect to FTP using correct credentials with the below error message –
Status: TLS connection established.
Command: USER username
Response: 331 User username OK. Password required
Command: PASS *************
Response: 530 Login authentication failed
Error: Critical error: Could not connect to server
1. Make sure the FTP service is properly configured and working on server.
2. Try to reset the existing password and give a try.
3. Still no luck then restart the FTP service and it’ll start working.
