# When to configure proxy settings
Configure proxy settings for Elastic Agent when it must connect through a proxy server to:
- Download artifacts from `artifacts.elastic.co` for subprocesses or binary upgrades (use [Agent binary download settings](/elastic/docs-builder/docs/3016/reference/fleet/fleet-settings#fleet-agent-binary-download-settings))
- Send data to Elasticsearch
- Retrieve agent policies from Fleet Server
- Retrieve agent policies from Elasticsearch (only needed for agents running Fleet Server)

If Fleet is unable to access the Elastic Package Registry because Kibana is behind a proxy server, you may also need to set the registry proxy URL in the Kibana configuration.
