Docker-compose up : Error while fetching server API version: ('Connection aborted.', ConnectionRefusedError(61, 'Connection refused'))

Add your user to docker group and try again.

sudo gpasswd -a $USER dockernewgrp docker

If you still have the problem, you may try after logging out and login back, or reboot. Or simply do:

sudo su $USER

Note: this may also happens if docker is not running on your machine. For linux with sytemd service manager, you could verify using command:

systemctl status docker.service

php docker api server docker-compose

just open Docker Desktop if you use a mac

php docker api server docker-compose

I had the same issue and error message. In my case i had to start and enable docker service.

systemctl start dockersystemctl enable docker
