Application space practiced hand, space can not open Web page, how to deal with

Application space practiced hand, space cannot open web page
I applied for free space in Germany, unexpectedly, I uploaded an htm file to the WWW directory, opened a two-level domain name, found the following error

Help: I think I uploaded to the root directory of the HTM file, should be typed in the domain name directly after the analysis of the HTM file, the viewer display, how not? Reasons and Solutions

The filename has to be the default index.htm or index.html try it out.
