Any advice on how to proceed?

Your docker engine is trying to contact the registry and having some sort of CDN, firewall, or corporate proxy issue trying to have a proper "conversation" with the registry. It's pretty similar to being on hotel or public WiFi that has a "walled garden" that hasn't been processed through yet.
Unless you have a persistent network issue, it could be temporal, and as someone else suggested a docker pull hello-world:latest may work. If you have a corporate proxy, you may have to make sure the Docker toolbox/Docker for Windows configuration has this proxy configured properly to have network access.

Docker pull giving connection reset by peer error

I have installed Docker on Ubuntu machine. I have problem with docker pull command, I am getting connection reset by peer error.
root#machine1:~# docker pull ubuntu
Using default tag: latest
Error response from daemon: Get https://registry-1.docker.io/v2/: read tcp 10.80.64.126:51404->54.152.209.167:443: read: connection reset by peer
command : docker images worked and gave empty result as no image is downloaded on docker host. But as this command is working, shows docker installed successfully.
REPOSITORY TAG IMAGE ID CREATED SIZE
My docker version is 1.13.1.
How can I solve this problem?

Unable to find image 'hello-world:latest' locally Docker

This is the first time I am trying to set up docker (version 17.09.0-ce). I have followed the all instructions from official site and this run ok on my machine (Windows 10 x64). When I type docker --version on console returns Docker version 17.09.0-ce, build afdb6d4. But i am trying execute docker run -t hello-world and this is the answer:
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.
my internet is from proxy, but I make a VPN and everything work perfectly except docker, I even install python packages using pip. what could be wrong?
I resolved this issue on windows 10 by resetting the DNS server to use the Google DNS fixed address: 8.8.8.8 (docker documentation)
This should resolve the issues for most.
For windows behind a proxy, you can do the followings to resolve this issue
go to your proxy setting under resources and enter your proxy credentials
username:password#yourdomain:port.
Important make sure to account for special character Unicode conversion
for example, if you have # in your password then you replace it with: %23
you can covert special characters via site.
I resolve this modifing daemon.json and put my proxy there. In case of Windows on Docker Desktop, go to Resources, Proxies:
For users in China, I recommand this answer.
You need to add a valid address to pull the image "hello-world".

can't pull docker images from nexus proxy

The nexus is configured at 8444 for internal hosting and the 7001 for the external proxy. I am able to pull images from 8444. But can't pull anything from the internet. The nexus is pointing to https://registry-1.docker.io in the proxy settings. Any suggestions?
$ docker pull x.com:8444/hello-world
Using default tag: latest
latest: Pulling from hello-world
c04b14da8d14: Pull complete
Digest: sha256:a18ed77532f6d6781500db650194e0f9396ba5f05f8b50d4046b294ae5f83aa4
Status: Downloaded newer image for x.com:8444/hello-world:latest
$ docker pull x.com:7001/node
Using default tag: latest
Error response from daemon: unknown: unknown
(there is no error log showing in nexus for this pull)
I found the answer myself. In the configuration, need to use
"Use Docker Hub"
option in the Proxy->Docker index.
I used "Use proxy registry (specified above)" which doesn't work.

Unable to pull docker image, getting 'remote error: access denied'

I'm trying to check the installation docker pull hello-world
But getting the following error:
Pulling repository hello-world
Get https://index.docker.io/v1/repositories/library/hello-world/images: remote error: access denied
I have CentOS 6.5
Docker version 1.7.1, build 786b29d/1.7.1
I'm in a corporate network but curl https://index.docker.io/v1/repositories/library/hello-world/images forks fine.
What might be the issue?
Thanks in advance!
I got this error while I was trying to pull mongodb image instead of mongo.
So make sure image name is correct. The very same error message happens on both run and pull commands.
Had the same problem & error on the host working via proxy.
In essence - if you are behind an HTTP proxy server, you will need to add proxy configuration in the Docker systemd service file.
https://docs.docker.com/engine/admin/systemd/
(See at "HTTP proxy" section).
This helped me.
Did you add your user in docker group
https://docs.docker.com/engine/installation/linux/centos/#/create-a-docker-group
Otherwise, you should execute docker command with sudo before
docker pull hello-world
