Problems running the rails server with vagrant

I created a Xenial Xerus 64x box with the vagrant, installed the rvm with rails.

I'm running the server on the quiet VM, I can access the VM rails running there, but I can not access from my local browser.

I had already used vagrant other times but I always managed to upload the application using rails s -b 0.0.0.0 and in my local browser I open localhost: 3000.

But this VM I created is not working.
