nmap shows port 8080 is filtered even though it's opened. How can I open it?

I am using Ubuntu virtual host to run a tomcat based application that uses the port 8080, 8009, and 8000. The network admin has already opened the ports and when I run nmap on localhost it shows that they are opened.

$ nmap localhost
Starting Nmap 7.60 ( ) at 2020-02-10 12:46 UTC
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00023s latency).
Not shown: 995 closed ports
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
3306/tcp open mysql
8009/tcp open ajp13
8080/tcp open http-proxy

However, running nmap on from my machine, using the IP address shows me they are filtered.

$ nmap 120.xxx.xxx.xxx -p 8080
Starting Nmap 7.60 ( ) at 2020-02-12 10:36 EAT
Nmap scan report for 52.157.164.120
Host is up (0.17s latency).
PORT STATE SERVICE
8080/tcp filtered http-proxy
Nmap done: 1 IP address (1 host up) scanned in 2.39 seconds

I don't have access to the azure interface, and there is no firewall enabled on the ubuntu vm.

What could be filtering the request? What can I do?
