A change takes effect on the next sandbox you create or restart; already-running sandboxes keep the proxy they were created with. Daemon scope (proxy.daemon, no_proxy.daemon, and the daemon side of proxy and no_proxy) is resolved once when the daemon starts. A change requires a daemon restart.\n\nThe DOCKER_SANDBOXES_ environment variables are a separate case. They control sandbox traffic only, as described in Environment variables, but sbx reads them from the daemon's environment as the daemon starts, so changing one also requires a daemon restart.\n\nWhen a system or PAC proxy is in use, sbx still tracks OS-level proxy changes (such as switching networks, connecting a VPN, or updated PAC contents) live.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
