Fresh Droplet loads a lot and browser returns "server not responding"

I have just created a droplet, installed jre, jkd and maven. I uploaded a SPRING project that was running perfectly on my machine in Idea editor, but when I access <ip>:8080, it loads some long time and then browser returns “server not responding”. Why is that?

All that I did was just fetch from GitHub. Also, this is how I am starting the app:

mvn clean install java -Xverify:none -Djava.security.egd=file:/dev/./urandom -jar target/app-0.0.1-SNAPSHOT.jar

Also, to permanently deploy the app, all that I do is add an & at the end of the second command. Is it fine? Do you recommend that?

Hi there @TheJavaDevv2,

If you have a firewall like ufw make sure to open port 8080:

ufw allow 8080

Also I could suggest using netstat to check if the application is actually listening on 0.0.0.0:8080 rather than 127.0.0.1:8080 as if you want it to be accessible from the outside world, it has to be 0.0.0.0:8080:

netstat -plant | grep 8080

Regards, Bobby
