oxidized: "source returns no usable nodes" error after docker host reboot

Hello everyone, I know, this error appears a lot of times here, but I couldn’t find any solution. I read my config files multiple times to see if there is a typo somewhere, but didn’t find anything.

I installed oxidized and LibreNMS a few weeks ago on the same server, but each in its own docker container (multiple docker container for libreNMS). All the container are in the same docker network, which is a bridge.

Everything worked fine until I restarted my host server. Since then, Oxidized is unable to start, with the following error :

I, [2023-08-02T09:12:01.964453 #2635]  INFO -- : Oxidized starting, running as pid 2635
I, [2023-08-02T09:12:02.020787 #2635]  INFO -- : lib/oxidized/nodes.rb: Loading nodes

source returns no usable nodes

Here is my oxidized config file :

    map:

    repo: "/home/oxidized/.config/oxidized/git-repos/default.git"
  file:
    directory: "/home/oxidized/.config/oxidized/configs"

If I set default: csv instead of default: http in the input, everything works fine. I already renewed the LibreNMS API token multiple times, with multiple rights (Admin and Global Read) with no success. If I set debug: true in the oxidized file, I don’t have any logs in the logs folder.

Running curl from the oxidized container to the libreNMS container works fine, I get the list of all the devices which are in LibreNMS :

root@1835b2f94b92:/home/oxidized# curl -H 'X-Auth-Token: token' http://docker_host:8001/api/v0/oxidized
