I can't jailbreak on ios 7.0.4. What should I do?

Question

iPhone

Hello. I can't jailbreak on ios 7.0.4. Downloaded evasi0n 7 version 1.0.5 (of course on mac). Then I connected the iPhone 4. I pressed the jailbreak button (which came out on the mac'a screen). It seems that I have the Internet, but immediately, after 2-3 seconds it gives out:
"ERROR: Failed to retrieve package from the internet"
If you know what to do, please HELP me!!!
