my host are edited while connecting (OS Error: No address associated with hostname, errno = 7)

there is something strange when I use this plugin, I try to connect using the host homedev.dtp.net.id but an error appears that hostdev.dtp.id is not found. yes the host changes from homedev.dtp.net.id to homedev.dtp.id. what happen?

this is my code:

const testOptions = PusherChannelsOptions.fromHost(
      scheme: 'ws',
      host: 'homedev.dtp.net.id',
      key: 'mykeyxxxxxxxxxxxxxxxx',
      // port: 443,
    );

    client = PusherChannelsClient.websocket(
      options: testOptions,
      connectionErrorHandler: (exception, trace, refresh) async {
        print(exception);
        print(trace);
        refresh();
      },
    );

    unawaited(client.connect());

and this is error appear:
