Hi,
I have found what cause this problem after compile a tomcat with some logs.
In RemoteIpValve.java’s method ‘invoke’, it check if protocolHeader is

setPorts method and use the default port (80) of http

Hi Hua,
You are right, when tomcat listening port 80, then getServerPort return
10001.

The problem can be related to nginx, nginx received a http traffic on 10001

take a look in

When the tomcat listen 8080 and nginx listen 80.
Nginx has set ‘proxy_set_header Host $http_host’.
What is the value of $http_host?
The $http_host is ‘externalIP:10001’
