I suspect there is a problem with Test 6/6 of this challenge.  Instead of checkio("04704072126132480B42F66E6AF67572205E5F5E"), it should be checkio("04704072126132480D42C3B66E6AC3B67572205E5F5E").  You will see in the commands in the Python console in the attached screenshot that, as is, the ö is misencoded as '\xf6', when in fact it needs to be '\xc3\xb6' according to the utf-8 standard.
