@rcsinambela Please make sure that the docker daemon is running and is accessible.

As you can see error happens on self.docker_client = aiodocker.Docker(), and that is mostly likely because daemon isn't running.

My Docker daemon is always running — I’ve confirmed it using docker ps and systemctl status docker. I can also run containers manually without any issues.

I also noticed that in previous issue (#347), some users encountered similar problems when enabling emulators for LFI, CMD, or Template Injection. Could it be related to that? Let me know if there’s anything else I can check or share.
