What steps will reproduce the problem?

  1. Code: Server server = new Server(); server.start(); server.bind(17771, 5000); Client client = new Client(); List<InetAddress> addresses = client.discoverHosts(17771, 5000); System.out.print(addresses);
  2. Run Code on two Computers which are in the same network
  3. Both PCs are able to create, start and bind the servers (without any errors)
  4. Both PCs print [](Empty list). Also, when I press a refresh button (which executes "List<InetAddress> addresses = client.discoverHosts(17771, 5000); System.out.print(addresses);" after the Servers were created on both PCs) then I get a "[]" message again. No Hosts found... Help is appreciated :) What is the expected output? What do you see instead? What version of the product are you using? On what operating system? Please provide any additional information below.

Is there any way to edit the ticket? I forgot to remove the last lines.

Some news/fix/tips about that problem?

Some routers block broadcasts. Also note it only works on a LAN with the same subnet.

Also it might not work on WLAN, depending on the client-isolation-settings of the hotspot.
