Java web app deployed and running but I cant access it on browser

It took me 2 full days to deploy my java web app on digital ocean(D.O). My web app is a Java jersey maven project, using payara glassfish server. It’s a REST app with an HTML form as a front end, there is no database, it’s just a simple calculator where the user can input and get a output.

What I did so far? I installed the java environment, glassfish, and maven in the D.O droplet. Then clone my project into the droplet, run a maven clean install, then get the WAR file and deployed it successfully on glassfish. Then started the glassfish server successfully, and now when I go to {dropletIP}:4848 I’m able to have access to my glassfish admin console, from there I see that my Java web app is successfully deployed and running. So all looks really good and this indicates that my app is online on the droplet and ready to be accessed from anywhere in the world.

The problem:

When I go to any of these URLs :

• {my_dropletIP}:8080
• {my_dropletIP}:8080/projectName
• {my_dropletIP}:8080/projectName/myHTMLForm.jsp
• {my_dropletIP}:8080/applications/projectName
• {my_dropletIP}:8080/applications/projectName/myHTMLForm.jsp

I tried these URLs using http and https.

When I try to access these URLs it just doesn’t work, it keeps loading, and then it shows this:

This site can’t be reached “dropletIp” took too long to respond. Try: Checking the connection Checking the proxy and the firewall Running Windows Network Diagnostics ERR_TIMED_OUT_

The problem is that I don’t have access to my web application.

note: The project works perfectly locally, and the path to access it is:

• http://localhost:8080/projectName/myHTMLForm.jsp

Please help, thank you! :)
