Hi @chapteradmin,
Thanks for sending that over. That’s the blocking page somebody potentially violating one of your Wordfence rules would see.
Do you know if they’re trying to retrieve a lost password, typed their password incorrectly a number of times or are using a username that you choose to block (or are mistyping their username)?
These are settings you can check for their leniency/strictness under Wordfence > All Options > Brute Force Protection and Wordfence > All Options > Rate Limiting. You may find that your settings are too strict, or there may be a misunderstanding over their username that is causing this lockout to occur when Immediately lock out invalid usernames is checked.
You can read more about these settings to assist your decisions at:

Thanks,
Peter.
