Message: IP Address is Banned

When accessing CAS, you are permitted a limited number of login attempts before your browser's IP address will be locked out ("banned").

The login credentials include:

  • Your Sign-in Name

  • Your Sign-in Password

  • Your 2FA code (if implemented)

If you use LastPass or another online password storage utility, it may attempt to log you in automatically with an old 2FA. This will fail, and you'll exceed the threshold resulting in your IP being banned - without any effort on your part!

Failing to correctly enter all 3 credentials 5 times will result in a ban:

Password requirements:

  • 12+ characters,

  • includes at least one digit,

  • includes at least one special character,

  • includes at least one lowercase + one uppercase characters.

Solution 1: GUI

Contact a CAS administrator to reset your password.

  • This action also unbans your IP.

Solution 2: CLI

First, determine your browser's IP address by visiting:

  • This will reveal the offending IP address of your browser.

    • In this example, we'll use 123.456.789.1 as your browser's “Public IPv4” address.

Login to the CAS CLI, and type:

sudo /batm/batm-manage unban-ip 123.456.789.1

CAS should report success, and you may login to the GUI again.
