+## [Unreleased]
+
+### Added
+
+- Configurable HTTP request timeout for Nexus Dashboard: `--request-timeout`, `ND_REQUEST_TIMEOUT_SECONDS`, or `request_timeout_seconds` in YAML (default 60 seconds). Previously the 60-second timeout was hard-coded, so a cluster that answered slowly failed every command with `httpx.ReadTimeout`.
+
 ## [0.2.0] - 2026-09-11
