 ### `rekey_timeout_interval`
-- **Default:** `150s`
+- **Default:** `180s`
 - **Environment Variable:** `WG_PORTAL_BACKEND_REKEY_TIMEOUT_INTERVAL`
 - **Description:** The interval after which a WireGuard peer is considered disconnected if no handshake updates are received. 
-  This corresponds to the WireGuard rekey timeout setting of 120 seconds plus a 30-second buffer to account for latency or retry handling.
-  Uses Go duration format (e.g., `10s`, `1m`). If omitted, a default of 150 seconds is used.
