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)
Send data to {es}
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.
