Re: Camel 4.21.0 netty-http with Spring XML

Mon, 31 Aug 2026 11:08:04 -0700 

For some reason no matter what options I set and try, I receive the same error 
when implementing a Camel Netty-HTTP route.  Does anyone see, or know where my 
mistake is?


The error reads

    This page isn't working

    192.168.2.32 didn't send any data

    ERR_EMPTY_REPONSE


Here are the settings I have set for my netty-http route

I looked through my log files and can see that netty-http is loading and 
binding to the proper port.  I have also performed an nc -zv 192.168.2.32 8443 
and receive a response.
