Tomcat is running on port 8080, but unable to access remotely using IP address?

Solution 1
Please check if port 8080 is accessible from outside. port could be blocked. Check your firewall settings and open the port for http request.
Solution 2
You have to setting NAT for your router to connect from the internet.
You don't need to do that if you connect from lan.
I checked and your port is closing.
Use this tool to check http://www.yougetsignal.com/tools/open-ports/
Or http://www.canyouseeme.org/
Solution 3
-
disable firewalld:
# systemctl stop firewalld # systemctl disable firewalld replace localhost with a valid IP that can be exposed externally in server.xml

I have freshly installed apache-tomcat-7.0.62 on my server. When i start tomcat it start with no errors, but when i want to access it using browser it says page is unavailable. I have used following command to check whether tomcat is running correctly or not :-
netstat -ntlp | grep LISTENand following is the output : -
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN -
tcp 0 0 127.0.0.1:8005 0.0.0.0:* LISTEN 19430/java
