"damon i got problem when use cloudeflare my sitemap status at google it's warning but when i not use cloudflare the sitemap back normal again"

Can you send us details (the error message you're getting, etc.) from Webmaster tools? You can contact us here. Google did have a very brief issue in early November crawling some sites, but this issue has long since been resolved. We probably need to reach out and make sure there isn't some other issue now.

Note for other readers:
I have some tips for troubleshooting CloudFlare problems that you should read.
