Why won't the Native Mac version of Pangu work on my iPhone 5c?

[iMore Question]

I'll go to do the jailbreaking (Note: everything is up to date; my iTunes, and the pangu. My iPhone is at the proper version as well, 8.1.) and it'll just say "Unable to get Jailbreaking resources, please check your network". PLEASE HELP!

iOS 8.1.3? That one can't jailbreak.
