'docker container not able to reach some of host's ports

I have a stack with docker-compose running on a VM.

Here is a sample output of my netstat -tulpn on the VM

Proto Recv-Q Send-Q   Local Address             Foreign Address         State      
tcp        0      0   0.0.0.0:9839              0.0.0.0:*               LISTEN     
tcp        0      0   127.0.0.1:8484            0.0.0.0:*               LISTEN

The docker is able to communicate with port 9839 (using 172.17.0.1) but not with port 8484.

Why is that?

dockernetworkingnetstat
