Before you change production

This page includes public source URLs in the imported troubleshooting record. Compare those references with your version and environment before applying changes.

Reproduce the smallest failing action and save non-secret logs before changing configuration.
Check versions for Docker, related SDKs, package managers, CI runners, and hosting providers.
Change one setting or dependency at a time, then rerun the same failing command or request.
Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

TLS handshake timeout when using docker pull is a Docker failure pattern reported for developers trying to fix docker pull command hanging/failing with tls handshake timeout — diagnose whether registry is reachable, certificate issues, or network proxy interfering with tls negotiation. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

GitHub issue #6062 in docker/cli (Dalzhim, May 2025, version 28.1). Specifically about TLS handshake timing out during docker pull, distinct from general daemon-not-running errors. Affects enterprise CI/CD pipelines where image downloads are critical path. Docker Enterprise customers pay for private registries — pull failures directly block deployments.

Common causes

GitHub issue #6062 in docker/cli (Dalzhim, May 2025, version 28.1). Specifically about TLS handshake timing out during docker pull, distinct from general daemon-not-running errors. Affects enterprise CI/CD pipelines where image downloads are critical path. Docker Enterprise customers pay for private registries — pull failures directly block deployments.

Quick fixes

Confirm the exact error signature matches TLS handshake timeout when using docker pull.
Check the Docker account, local tool state, and provider configuration involved in the failing workflow.
Verify the model name, local service connectivity, and network access before retrying the model pull.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

Capture the exact error message and the command, editor action, or request that triggered it.
Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
Review the source evidence below and compare it with your environment.
Apply one change at a time and rerun the smallest failing action.
Keep the working fix documented for the team or deployment environment.

How to prevent it

Keep provider/tool configuration documented.
Record non-secret diagnostics such as tool version, provider name, model name, and command path.
Add a lightweight check before CI or production workflows depend on the tool.

FAQ

What does TLS handshake timeout when using docker pull mean in Docker?

TLS handshake timeout when using docker pull indicates the workflow described by "Docker pull fails with TLS handshake timeout when pulling images from registry" failed in a Docker context. Start by confirming the exact signature and the component that emitted it.

What should I check first for TLS handshake timeout when using docker pull?

Check whether this cause matches your environment: GitHub issue #6062 in docker/cli (Dalzhim, May 2025, version 28.1). Specifically about TLS handshake timing out during docker pull, distinct from general daemon-not-running errors. Affects enterprise CI/CD pipelines where image downloads are critical path. Docker Enterprise customers pay for private registries — pull failures directly block deployments.

Is the TLS handshake timeout when using docker pull guidance source-backed?

The "Docker pull fails with TLS handshake timeout when pulling images from registry" page is labeled source-backed. It has 1 public source URL from github.com, so use that evidence status when deciding how much additional verification you need.

When should I avoid the quick fix for TLS handshake timeout when using docker pull?

For "Docker pull fails with TLS handshake timeout when pulling images from registry", avoid applying "Verify the model name, local service connectivity, and network access before retrying the model pull." when the error text differs, the affected version or provider is different, or the change would touch credentials, billing, DNS, production deploy settings, or irreversible data.

What should I collect before debugging TLS handshake timeout when using docker pull?

For "Docker pull fails with TLS handshake timeout when pulling images from registry", collect the failing Docker command or request, non-secret configuration, versions, timestamps, request IDs when available, and the smallest reproduction that still triggers the signature.
