Hi Team,

We are able to login but once in a week we are getting user locked out error.
When we are getting 401 or 403 error user is able to login and new session is created but once in a week user is not able to get new session and user locked out. We are getting below error.
Error: INVALID_LOGIN: Invalid username, password, security token, user not active, or user locked out
Could you please let us know what changes we need to do.
