Cannot access Tomact 9 from browser


I installed Tomcat 9 on my dorplet with Ubuntu 16.04 following this tutorial


I’ve changed the default port to 8181 because I have another service running on 8080 and started the service. If I check with

sudo systemctl status tomcat

it is running just fine.

If I check the ufw status the respons is good.

Status: active

To Action From

8181 ALLOW Anywhere
8181 (v6) ALLOW Anywhere (v6)

But when I try to reach the server in my webbrowser I get “Safari can’t open the page http://<my_IP>:8181 because Safari can’t connect to the Server <my_IP>”.

What could be the problem?

Hi @imeyer1

Can you run this command to make sure it’s listening on right port, and on the outside interface and not just localhost:

sudo lsof -iTCP -sTCP:LISTEN -P
