Code Snippet:

client = SsdpClient.create();
        DiscoveryRequest specificDevice = SsdpRequest.builder()
                .serviceType("urn:schemas-upnp-org:device:basic:1")
                .build();

        client.discoverServices(specificDevice, new DiscoveryListener() {
            @Override
            public void onServiceDiscovered(SsdpService service) {
                fillAdapter(service);
                Messages.log("Found service: " + service);
            }

            @Override
            public void onServiceAnnouncement(SsdpServiceAnnouncement announcement) {
                setMsg("Announcement: " + announcement.getOriginalResponse().toString());
            }

            @Override
            public void onFailed(Exception ex) {
                setMsg("Fail: " + ex.toString());
                ex.printStackTrace();
            }
        });

Hello,

thanks for the issue. That means you are binding to a port already used on the device. Is your device already listening on the specific port ?
You may use a different port using the options.
