Let me start with a little background. I have 3 web servers, one localhost, one public for development, and one public for production. On my localhost I am able to access the api with my hapikey and retrieve the correct data. This is also the case on my production server.
However, on my development server, when I try to access the API I get the following message
You don't have permission to access "http://api.hubapi.com/forms/v2/forms?" on this server.<P> Reference #18.5f0ad717.1512669680.1e758e7b
This occurs inside PHP, as well as when I try to CURL the API endpoint. This error is only occuring on my development server and works fine on my other servers.
