No solution mentioned above was solved my problem. My problem was different.

First check is your port is disabled in firewall. Go to Control Panel -> Windows Firewall -> Advance Settings -> Inbound Rules and see any port is blocked.

A sample image is below:

If so then you can unblock the port by following steps:

Step 1:

Here you can see that the port is blocked.

Step 2: Allow the connection -> Apply -> Ok.

That's solved my blocked problem. Happy coding :) :)

Windows Firewall cause issue after  uninstalling Oracle JDK and installing OpenJDK on Windows Server 2008 R2   Tomcat 7 and Tomcat 8 not access on other machine after this   Follow below path to add new rule   -- gt  Windows Firewall with Advanced Security on Local Computer  -- gt  Inbound Rule   -- gt Add New Rule        with specific port you have required for Tomcat application

If you are trying to access your web app which is running on apache tomcat server  it might be working perfect while you are trying to use it on     http   localhost 8080    it will not work same if you are trying to access it on your mobile device browser for ex  chrome using     http   192 168 x x 8080   so if you want to access via ip address on your remote mobile device   do following settings   Open server xml file  Change    lt Connector connectionTimeout  20000  port  8080 protocol  HTTP 1 1  redirectPort  8443   gt     to        lt Connector connectionTimeout  20000  port  8080  protocol  HTTP 1 1  redirectPort  8443  address  0 0 0 0    gt     Save the file Stop and restart the server Now access on your mobile device using ip address http   192 168 1 X 8080    You are good to go

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

Check your windows-firewall feature in control panel  Outbound and inbound port should allow port 8089   or write a new rule for this- Right hand side  actions - new rules   it worked for me

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

I was also facing same problem on Amazon windows EC2 instance   Windows Server 2012 R2    Then I figured out   it was local windows firewall preventing it    I opened port 80   defined port for website   using windows Firewall with Advance Security     It resolved the issue

You need allow ip based access for tomcat in server xml  by default its disabled  Open server xml search for     lt Connector port  8080  protocol  HTTP 1 1              connectionTimeout  20000              URIEncoding  UTF-8             redirectPort  8443    gt    Here add a new attribute useIPVHosts  true  so it looks like this    lt Connector port  8080  protocol  HTTP 1 1              connectionTimeout  20000              URIEncoding  UTF-8             redirectPort  8443             useIPVHosts  true    gt    Now restart tomcat  it should work

New versions of application servers removed the ability of binding to your entire network interface and limited it just to the local interface  localhost   The reason being was for security  From what I know  Tomcat and JBoss implement the same security measures    If you want to bind it to another IP you can explicitly set it in your connector string    Tomcat  address  192 168 1 100  JBoss  you pass in a -b 192 168 1 100 as a command line     Just remember that binding 0 0 0 0 allows anyone access to your box to access that server  It will bind to all addresses  If that is what you want  then use 0 0 0 0  if it isn t then specify the address you would like to explicitly bind instead   Just make sure you understand the consequences binding to all addresses  0 0 0 0

Thanks for all answers  For me it was a different issue  I had to set my wireless network to  quot private quot   I only need tomcat for network internal use  For some reason although firewall rule was set to allow for all  it does not allow access from within the same network if set to public  Changing settings in server xml were not needed in this usecase

Firewalls are often the problem in these situations  Personally  the Mcafee enterprise firewall was causing this issue even for requests within the network    Disable your firewalls or add a rule for tomcat and see if this helps
