Node global tunnel and loggly and linkerd

I'm using linkerd and have to use global tunnel to proxy everything via localhost:4140. The problem is that this seems to cause loggly to stop working. As soon as the global tunnel is active, loggly doesn't receive any messages. How can I change it?

globalTunnel.initialize({
  host: 'localhost',
  port: 4140
});

I have seen, that I can pass a proxy variable in the config for the loggy instance.

var logglyStream = new Bunyan2Loggly(logglyConfig);

Thanks for the help.
