图纸为啥下载不了？？？？

我想下载图纸，可是每次点击“下载”，就出现如下提示：



Content Encoding Error (content_encoding_error)


Server response could not be decoded using encoding type returned by server.
This is typically caused by a Web Site presenting a content encoding header of one type, and then encoding the data differently.

For assistance, contact your network support team.


哪位帮我解决一下啊。。
谢谢各位专家。
