If you read the readme file (first bullet under Configuration Issues) or noted the console output during startup, such as: 17:57:49,046 INFO [Http11Protocol] Starting Coyote HTTP/1.1 on http-127.0.0.1-8080 you would know the 4.2 binds to localhost by default. If you want the 4.0.x behavior (which binds to all addresses), bind to 0.0.0.0: run -b 0.0.0.0 or you can bind to a specific address.
