Configure TYPO3 Crawler Extension

I followed this tutorial to index some files in the fileadmin. Now I am at the point "Then manually process the entry: (...)". The problem is that I get this errormessage when I click on the green "refresh-Button":

Can someone tell me what am I doing wrong and why I am not authorized to Crawl through my page as the message: Error: 401 Authorization Required Authorization R... tells me.

By the way: i did not forget to add the user: _cli_crawler .

Thanks in advance
