When you run this command, docker tries to "download" matchering. Docker is telling you that it could not download matchering because it ran into a timeout. This can have many reasons. Maybe you were not connected to the internet at the time you tried to run the command. Maybe you are behind a proxy/firewall (e.g. in a corporate environment) that prevents access to the docker contrainer registry (think about it as a download server). Maybe the docker registry had a temporary downtime when you tried. Maybe you were using a VPN at the time (and the docker registry is blocking your VPN providers egress IP).

My suggestion to you is:
make sure you have internet connectivity, disable VPN, use a mobile network for internet that does not sit behind a proxy/firewall and then retry again.
