Cannot access Tomact 9 from browser

Hi,

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

[https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-8-on-ubuntu-16-04]

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?

Thanks
