SSL connection error

[konradmoesch]

I tried using your tool at TUHH (https://e-learning.tuhh.de/studip), but only get The SSL connection could not be established, see inner exception. Authentication failed, see inner exception I dont know how to provide more information, --debug and --verbose did not change anything.

Providing User and Pass gives me the following stack trace:

Sieht so aus also würde dein Client der Zertifikatskette des Ziel Systems nicht vertrauen. Sind die korrekten Root und Intermediate Zertifikate im Zertifkatsstore bzw. welches Betriebssystem? Alle Updates installiert?
