Unable to create a docker network

Question

I managed to start the Docker application without problems, but suddenly I get this error:

Failed to parse pool request for address space. LocalDefault pool "subpool" ": could not find an accessible, non-overlapping IPv4 address pool between the default values ​​for network assignment

I am running Docker 1.12.6.

How to fix it?

Answer 1

Turns off the limit for the number of simultaneously active Docker networks, and I click this limit.

I had a problem deleting all my networks:

docker network ls -q | xargs docker network rm 

Answer 2

I had this problem when starting the OpenVPN client, which was also my default route. The OpenVPN client stop worked on the issue.

Answer 3

 docker-compose down docker network prune
