title: How can I configure Charles proxy for SSL tracing of Google ad requests?
body: <p>In the past, I've been able to use Charles to view HTTPS traffic for requests made to Google ad services. Today, I am no longer able to see the requests made to <a href="https://pubads.g.doubleclick.net/gampad/ads" rel="nofollow noreferrer">https://pubads.g.doubleclick.net/gampad/ads</a>, in order to confirm that my ad params are correct. For example, I want to be able to see the "sz" param to make sure I'm looking at a banner request (320x50), and I want to see the "iu" param to make sure the full ad unit path is correct.</p>
  
  <p>This problem is specific to Google ad traffic. I am able to see the details of other HTTPS requests made by my app. I've jumped through the hoops to configure SSL support in Charles, I've installed the Charles SSL certificate on my device, and I've configured my app to accept third-party root certificates in order to allow for visibility into SSL-proxied traffic. But I'm not seeing the gampad requests my app is making to Google's ad server, where before I used to see them.</p>
