Hi, I installed Docker on my Fedora 37 and the dns resolution does not work. Here’s the result when I try to build the zola deploy action:

I installed docker with dnf install docker. The only way of making the dns resolution work I found is passing the --network host parameter. With this parameter I can build the container manually, but it does not help in the real use I want to give docker, for a Forgejo runner. I need docker to work correctly without passing any extra parameter.
I never modified the docker configuration before getting this error. To try to fix it, I tried specifying the dns servers on /etc/docker/daemon.json, restarting docker, restarting the system, disabling dnsmasq, and putting DOCKER_OPTS="--dns 8.8.8.8 --dns 10.252.252.252" on /etc/default/docker. Nothing works.
I tried installing docker on another system with PopOS and worked out of the box. Does someone know what could be the problem?
