404 error when fetching prometheus metrics under docker

Grafana Configuration
1

I just set up grafana and prometheus using docker and grafana says that the prometheus data source is working and connected. Yet when I try to press the metrics button, I get a 404 error.

Its trying to access :

remote_addr=172.18.0.4

Looking at prometheus/metrics we can see them listed
