Getting "wrong username or password" after an auth redirect


I have a Twitter application.
When user clicks “Sign in with Twitter”: I run a GET authorize/authenticate and redirect user to

  • If user is already logged in, Twitter page asks user to authorization. Everything is fine.
  • If user isn’t logged in, on top of the page this text appears “Something is technically wrong” “wrong username or password”. And Twitter page asks user to fill username and password. My visitors complains about the sentence on top. They say that they even didn’t fill their username and password but Twitter page says that wrong password. What creates this alert ? How can I prevent it ?

Except the "wrong username password warning everything works fine as this page:
But I need to disable that warning.
