For a few days I've been trying to solve this problem by searching on stackoverflow and other sites but I can't find it.
I currently have a spring boot application converted to jar running on a server. This application is accessible via a browser using the localhost on port 8080 by using tomcat which was directly integrated to my spring boot application.
The problem is the following:
We will tell here that the ip address of my server is 123.45.69.894
If I type :
localhost:8080/mypath
or if I type :
123.45.69.894:8080/mypath
in the browser of the server. I have this that appears in the console when I make the request :
2022-05-21 08:23:26.094 INFO 7536 --- [nio-8080-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring DispatcherServlet 'dispatcherServlet'
2022-05-21 08:23:26.094 INFO 7536 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet : Initializing Servlet 'dispatcherServlet'
2022-05-21 08:23:26.109 INFO 7536 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet : Completed initialization in 15 ms
and everything works well.
But if I type,
123.45.69.894:8080/mypath
in the browser of another computer it doesn't work anymore and I have a connection time out error and nothing appears in the console.
I have already checked if the firewall doesn't blocked the port 8080. But the problem is not there.
I have also on the port 80 an IIS web site, the problem can come from there ?
I have already looked at these articles for example but that doesn't work for me :
how to deploy Spring boot application in IIS
Apache Tomcat not accessible from outside
Does anyone know where the problem might come from and how to solve it?
From the remote machine, try pinging your IP address. If it times out there is definitely a firewall issue between the machines. If ping works, try telnet IP port. If on Windows you may need to enable telnet from setup/applications. If telnet connects, the there will be no action until you hit cntrl square bracket. If that works then everything should work ok.
