Wrong email or password error on email-password pair login try

Hi, I have trouble with login. When I try to login with email, I use email which I created the auth0 account with its password. Each time I got wrong email or password error, few trial later my account blocked… I changed my internet connection but then I got the same “wrong password or email” error… Below the react code. I need to solve this asap! Thanks.

Note: I also tried to reset password but there was no action on click of sent email to reset password button… Even I get the response of email sent I didnt receive any email.
