SFTP Authentication Failed, Need to retrieve password

[wormsunited]

Hi there,

I am using Filezilla to access SFTP, for some way, i cannot access with the root password, i did checked the /root/passwords.txt file and it matches the one i input to login using root as a username.

When i try to connect, i get Authentication Failed. Unfortunately... 

Code:

Status: Waiting to retry... Status: Connecting to xx.xxx.xx.xxx... Response: fzSftp started, protocol_version=8 Command: open "root@xx.xxx.xx.xxx" 22 Command: Pass: **************** Error: Authentication failed. Error: Critical error: Could not connect to server

That is exactly what i get now. I did checked the file, but still cant connect to SFTP, any idea? Thanks in advance for your time and attention.
