If I try to download "http://www.fanfiktion.de/s/4a0b18160000c64e06514438" I get the following error message: 'NoneType' object has no attribute 'string'

debug output:

Is it possible related to the fact that I have to identify myself as adult on fanfiktion.de to read the story direct on fanfiktion.de?
To identify I need my personal ID card (not just to click on "Yes, I am adult" or similar)
