I upload images in PHP in the local test no problem, the server reported the wrong, what is the reason?

Object (Qiniu_error) #5 (4) {["Err"]=> string (+) "couldn ' t resolve Host ' upload.qiniu.com '" ["Reqid"]=> NULL ["Deta Ils "]=> NULL [" Code "]=> int (0)}

Server DNS issues.

Tie hosts

1. Do you configure host
2, the interface path is dead, not with the debugging environment changes and dynamic change.

That's a very clear tip.
Check the upload.qiniu.com domain name resolution
