Upgrade from 12.1.49.x to 50.x+ or 13.x re-captcha causes error at login page.
Setup for ReCaptcha on 12.1.50.x + or 13.0.x causes error at login page.
Error on login is "Error for site owner: Invalid Site Key"
ns.log has error message - 0-PPE-2: default AAATM Message 16977 0: "nFactor: Could not find matching captcha policy"

Resolution

When creating the authentication action for the Captcha policy, use Captcha authentication action type instead of Webauth.

Problem Cause

ReCaptcha on Netscaler as of 12.1.50.x and 13.x + uses a Captcha action as opposed to a Webauth action for the authentication policy action.
