 ### Fixes
 
 - Slack: honor ambient HTTP(S) proxy settings for Socket Mode WebSocket connections, including NO_PROXY exclusions, so proxy-only deployments can connect without a monkey patch. (#62878) Thanks @mjamiv.
+- Network/fetch guard: skip target DNS pinning when trusted env-proxy mode is active so proxy-only sandboxes can let the trusted proxy resolve outbound hosts. (#59007) Thanks @cluster2600.
