Docker Host Server SSH gets permission denied

@George I trie the docker system prune myself just now and received this error in the Host Server SSH within Wappler - any ideas?

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/prune: dial unix /var/run/docker.sock: connect: permission denied
