Can't access Tomcat using IP address

You need allow ip based access for tomcat in server.xml, by default its disabled. Open server.xml search for "

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           URIEncoding="UTF-8"
           redirectPort="8443" />

Here add a new attribute useIPVHosts="true" so it looks like this,

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           URIEncoding="UTF-8"
           redirectPort="8443"
           useIPVHosts="true" />

Now restart tomcat, it should work

You need to make Tomcat listen to 192.168.1.100 address also.

If you want it to listen to all interfaces (IP-s) just remove "address=" from Connector string in your configuration file and restart Tomcat.

Or just use your IP to listen to that address address=192.168.1.100 in the Connector string

If you are not able to access tomcat from remote, there might be reason that taken port is not open in your machine. Suppose you have taken 8081 port.

On Your windows machine:

Open Control panel-> windows Firewall-> Advance setting->Inbound Rules

Create a new rule: mention Port

Configure your port and then shutdown and start your tomcat and it will be accessible from remote as well.

That port issue majorly comes in AWS machines.

If it is still not working then please check with your administrator that selected port is open for public access or not, if not then open it.
