Before you start
Authentication tokens, image manifests and layers are separate stages; HTTP 429 often indicates a rate limit.
Step by step
- Check the official status or announcement page at https://www.dockerstatus.com/. A help page is not necessarily a live status monitor.
- Reproduce the Docker Hub issue on one exit and record its time, code, stage and duration.
- Pull one small public image and record whether authentication, the manifest or a layer download fails.
- Compare wired, Wi-Fi or another network while changing only one condition.
- If the app is slow but the browser works, compare app and system proxy settings for duplication.
- Authentication tokens, image manifests and layers are separate stages; HTTP 429 often indicates a rate limit.

Common questions
Can switching networks fix every Docker Hub error?
No. Account privileges, subscriptions, file permissions and service outages require separate checks.
What should I send to support?
Share the time, client version, redacted error code and minimal reproduction. Never share a password, token, cookie or one-time code.
