## TL;DR

Fixed in Renovate 14.3.20. If you hit a 406 from Artifactory with Docker image lookups, upgrade past 14.3.20.

1. Fixed in Renovate 14.3.20. The fix sends the correct Accept header when reading tag lists from registries, and handles the library/ prefix only for Docker Hub. If you hit a 406 from Artifactory with Docker image lookups, upgrade past 14.3.20. As a general rule, always use fully qualified image names (with the registry/repo path) when pointing Renovate at Artifactory instead of relying on Docker Hub naming conventions.

## When to use

You are seeing this: Renovate fails against a JFrog Artifactory Docker registry with a 406 error when fetching tags, while the same config works against Docker Hub. Use this skill when you run into "Renovate Artifactory 406 Error when fetching tags for Docker images".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.
