如何阻止远程请求

In our WordPress theme we check the user license with a wp_remote_get() request. Now some users reported back that they host didn't allow remote requests. My question is how can i test this myself locally for the development, how can i simulate to block remote get request.

Searched a lot but found nothing that works.

I use Apache, php and MySQL (latest versions)

Thanks!

My best try would be to edit the hostfile. For Mac the hostfile is located at

$ sudo nano /etc/hosts

And then i would add the following line and save.

169.254.1.1  yourdomain.com

To recreate your users problems.
