My Firewall Is Blocking YouTube-API Traffic. Which Exceptions Should I Configure?

Problem:

• I have code on my developer machine that can successfully publish a video to YouTube via the YouTube API.
• When I move this code to a QA machine, the firewall blocks the YouTube API communication.

Other Informatio开发者_StackOverflow中文版n: - I've been using Fiddler2, and it seems that the YouTube API needs to communicate with both YouTube.com and uploads.gdata.youtube.com.

My Question:

Which firewall exceptions should I configure to permit my web server to communicate with YouTube via the YouTube API?

Use Wireshark to inspect the network traffic.
