Tomcat端口已打开，但应用程序无法加载

Question

I would like tomcat to run in both ports, 8080 and 9000. Port 8080 works perfectly but that is not the case for port 9000.

Port 9000 is open and listening:

$ ufw status
To                         Action      From
--                         ------      ----
9000/tcp                   ALLOW       Anywhere 
9000/tcp (v6)              ALLOW       Anywhere (v6)

$ netstat -an | grep "LISTEN "
tcp6       0      0 :::9000                 :::*                    LISTEN 

I can connect to the port and get the index page

$ wget mydomain:9000
HTTP request sent, awaiting response... 200 OK
Length: 1887 (1.8K) [text/html]
Saving to: ‘index.html’

100%[=========================================>] 1,887       --.-K/s   in 0s      

I have added a connector into the con/server.xml in tomcat

<Connector port="9000" protocol="HTTP/1.1"
connectionTimeout="20000"
URIEncoding="UTF-8"
redirectPort="8443" />

But when I open the browser and type the address "mydomain:9000" the app is never loaded. It doesn't show any error, it just hangs there. I have checked the logs but no error is shown. I have no idea what the problem could be.Apache2 is running in port 80, but I am not sure if that is somehow related to the problem.

Any help is greatly appreciated...

确保所有防火墙都允许该端口上的客户端和服务器之间进行通信（双向-防火墙可以双向或双向屏蔽数据）。
