Doesn't seem to work on localhost

If I hit my web server on localhost:3000 I don't see anything in the console. If I instead go to 127.0.0.1:3000 and activate the plugin again, it starts working.

It works fine for me when using it on localhost (I use port 5000, but I doubt it has anything to do with that :))
