Docker: error response from daemon: grpc: connection not available

Question

Does anyone know what causes this error? Will this have something to do with my network settings?

(noob bit on the network front, please feel free to comment and point me in the right direction for the relevant data)

Get it when you try to do:

• any teams docker run
• any docker buildwith package updates (e.g. RUN apk update)

Specifications:

• Docker version 1.13.0, build 78d1802
• openSUSE Tumbleweed 20170505

Testing problem

Tried to use the following containers to no avail:

• Redis:latest
• alpine:latest
• python:3.4.6
• python:latest
• hello-world

Edit:

Dockers work fine - systemctrl status dockerreturns:

docker.service - Docker Application Container Engine
Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
Active: active (running) since Wed 2017-05-17 16:21:18 BST; 2 days ago
