NAT chain: ZONE_CONFLICT: 'br-mailcow'

Krillian

I’ve just rebooted my machine and now after running docker-compose up -d I get the following error:

WARNING: The WATCHDOG_NOTIFY_EMAIL variable is not set. Defaulting to a blank string.
Creating network “mailcowdockerized_mailcow-network” with driver “bridge”
ERROR: Failed to program NAT chain: ZONE_CONFLICT: ‘br-mailcow’ already bound to a zone

Any idea on how to fix this?

firewall-cmd –zone=trusted –remove-interface=docker0 –permanent

Seemed to have fixed it
