Hi,
Could you maybe describe your setup furthermore so we can help you? There simply isn’t enough information in your message for us to draw any sort of conclusion.
Also, you may want to check this post:
In particular, the following part:
Beware, for existing plugins already access this value like so, such as the rate-limiting plugin. This means, if Kong/ngx_http_realip_module is badly configured, this plugin will rate-limit based on a previous load-balancer’s IP address, instead of each individual client’s IP address, leading to a drastically different behavior than expected!
Your issue could be related. Or it could be something else entirely but for us to figure it out, we’d need more information.
