title: Google's Youtube Data API v3 - Why Is My IP Being Refused?
body: <p>I'm using PHP/curl to request a Playlist search and had everything working on my local machine.</p>
  
  <p>Now that I move the project onto my web server, I'm getting an error: </p>
  
  <p><em>There is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your API key configuration if request from this IP or referer should be allowed.</em></p>
  
  <p>I guarantee that:
  a) The Youtube data API is enabled in Google Developer Console
  b) The API Key is working (as the curl request worked from my local machine)
  c) I have done an external IP lookup on my domain name and entered the IP into the permitted IP addresses for this API key in Google Developer Console.</p>
  
  <p>So, given these things, why would I still be refused by Google with that error message?</p>
