Prometheus: Unable to access the Prometheus from browser

I have done with configuration of Prometheus on my ubuntu machine but unable to access it via browser. - PODS and services are working for Prometheus.
I tried accessing the Prometheus using following ways unfortunately nothing work for me:

1. localhost:9090

2. 172.31.37.100:9090 [Static IP of ubuntu machine]

3. 172.19.33.206:9090 [Default IP of ubuntu machine]

I am not sure what need to be done to make it work. Request you all to please suggest.
