Our customers often approach us with this error. Firstly, we check if the firewall service status using

systemctl restart iptables.service

If the service is down we restart the service.

Then, we check the iptables rules using the command

iptables -L

The docker firewall rules were missing thus it shows the error.

To resolve the error our Support Engineers restart the docker service. For instance, to restart the docker we use the command,

service docker restart

While restarting the Docker, it automatically creates the firewall rules. And we ensure to enable the firewall before restarting the docker.```
