Ubiquiti officially deprecated the Chrome extension version of the Discovery Tool due to changes in Google Chrome's application ecosystem. The standalone Java executable ( ubnt-discovery-v2.5.1.jar ) remains operational because it communicates directly with the network layer via User Datagram Protocol (UDP) broadcasts on port 10001. This bypasses browser-based security restrictions and handles multi-subnet environments efficiently. Prerequisites and Software Requirements
