On the Reporter, did try to create a new user and set the new user for the FTP service but issue still persist.
There are multiple proxies uploading the logs and one of the proxies had a wrong password causing a failed attempts and this had the Reporter to lockout the account.
On Reporter, there is a default setting to lockout the user after 5 failed attempts and this is affecting the other proxy access upload as well.
Disabling this option resolve the issue and below is the command:
#configure
(config)# authentication disable-user-lockout
