Building docker image fails with failed to fetch anonymous token, TLS handshake timeout

I got a problem while creating a docker image using docker build -t image_name .. When I execute it I get errors:

 => [internal] load build definition from Dockerfile 0.1s => => transferring dockerfile: 32B 0.0s => [internal] load .dockerignore 0.0s => => transferring context: 2B 0.0s => ERROR [internal] load metadata for 0.2s

This recently happened for me when running a build script for earthly/earthly.

OS: Arch Linux 5.14.8-arch1-1

Docker from official repository: Docker version 20.10.8, build 3967b7d28e

Solution (likely a Linux-only solution)

DNS was misconfigured for me. For some reason, docker pull golang:1.16-alpine3.14 worked fine but was failing when running the build script. This answer on r/docker helped.

Adding a DNS nameserver to my /etc/resolv.conf solved this issue for me:

cat /etc/resolve.conf
# Cloudflare
nameserver 1.1.1.1

Other Attempted Solutions

1. Disable Buildkit

From this answer to Docker build: failed to fetch oauth token for openjdk?, this did not solve the issue since I believe buildkit was required for the script I was running:

export DOCKER_BUILDKIT=0
export COMPOSE_DOCKER_CLI_BUILD=0

2. Manually pull image

3. Authenticating with Docker

The error looked like something that might happen when I was unauthenticated with hub.docker.com. After logging in with docker login --username <username> I still receieved the errors.
