Iptables docker chain block

Elastic Stack Elasticsearch
1

After installing Elasticsearch (port 8174) in Docker, I am experiencing packet drops in the Docker-related iptables chains, specifically:

  1. The DOCKER chain is dropping all traffic between non-bridge interfaces and Docker bridges (br-6c66a4eeb7d0 and docker0)
  2. This is preventing Kibana (port 5601) and Elasticsearch (port 9200) from communicating properly
  3. Removing all iptables rules temporarily fixes the issue

Can anyone suggest how to get around the iptables chain ? Thanks

Example :
Chain DOCKER (0 references)
pkts bytes target prot opt in out source destination
0 0 ACCEPT tcp -- !br-6c66a4eeb7d0 br-6c66a4eeb7d0 0.0.0.0/0 172.18.0.6 tcp dpt:5601
0 0 ACCEPT tcp -- !br-6c66a4eeb7d0 br-6c66a4eeb7d0 0.0.0.0/0 172.18.0.3 tcp dpt:9200
0 0 DROP all -- !docker0 docker0 0.0.0.0/0 0.0.0.0/0
0 0 DROP all -- !br-6c66a4eeb7d0 br-6c66a4eeb7d0 0.0.0.0/0 0.0.0.0/0
