Anyone have any idea what's causing this error? Is it going to be something to do with my network settings? 

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

Get it when trying to do:

* any `docker run` commands
* any `docker build` with package updates (e.g `RUN apk update`)

**Specs:**

* `Docker version 1.13.0, build 78d1802`
* `openSUSE Tumbleweed 20170505`

**Testing issue**

Tried running the following containers to no avail:

* `Redis:latest`
* `alpine:latest`
* `python:3.4.6`
* `python:latest`
* `hello-world`

**Edit:**

Docker service running fine - `systemctrl status docker` returns:

```
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

```

From `docker inspect`, containers are exiting with:

* `Exitcode 128`
* `"Error": "grpc: the connection is unavailable"`
