Hello!
My discourse instance is not working anymore (nothing has been done on my side).
In production.log, I have got this message:
Error connecting to Redis on localhost:6379 (Errno::ENETUNREACH) subscribe failed,
What I have tryied so far:
- Server reboot
- Update docker + server reboot + rebuild app
I am quite new with docker and discourse and so I do not see what else I can do
Host OS: centos 7
Proxy: Apache
Docker: latest version
On the host, I have fail2ban installed and firewalld.
In the firewalld log, I got strange lines:
2020-07-23 14:00:52 WARNING: COMMAND_FAILED: '/usr/sbin/iptables -w10 -t filter -X DOCKER-ISOLATION-STAGE-1' failed: iptables: No chain/target/match by that name.

Any help or advice would be appreciate
