We have not changed any settings, we added a feature. We had a lot of people who got locked out of their site because their server is behind a proxy and all requests appear to be coming from the same IP address. As a result every time there were many security exceptions that IP got blocked, therefore blocking everyone from accessing their site. Now we are detecting the HTTP headers which are tell-tale sign that your site is behind a reverse proxy, a cache, a CDN or other non-transparent network equipment which is forwarding IP traffic.
Please do as the message instructs you.
