Too many anonymous requests in proxy server

I am using kong 2.0.3 with the Postgres database by using kong chart 1.5.0 and deployed by Helm.
There are too many anonymous requests in kong proxy but I don’t know why it is.
Does anyone got it, or know why about it. Please help me to fix it. Many thanks.

This shouldn’t be anything to do with Kubernetes specifically. client closed connection while waiting for request is a generic error logged when a client aborts its request, i.e. it opens a connection but never sends a complete HTTP request.

This could be due to any of a number of causes, but it’s generally impossible to tell from the proxy end: all the proxy sees is the connection; any information about why the connection was closed after would only be available on the client. You’ll want to review the client logs and diagnostics for any indication of what’s going on.
