I switched to using the direct docker invokation (tweaked to fit with port constraints):

docker run -it \
--name nextcloud-aio-mastercontainer \
--restart always \
-p 6080:80 \
-p 8080:8080 \
-p 6443:8443 \
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
--volume /var/run/docker.sock:/var/run/docker.sock:ro \
nextcloud/all-in-one:latest

This gives me the same error.
