feed does not load

[fortsch]

Hello,
I recently "patched" my Java installation to be able to get HTTPS RSS Feeds.

While the patching seems to work (updating feeds not take a lot longer and no red crosses are shown anymore on HTTPS feeds) this one (which looks valid, when opening in FireFox Browser) seems to have problems being fetched:

I'm on Mac OSX Sierra with RSSOwl Version: 2.2.1, Build Id: 2013-12-30

Here is the exported log.

Anyone knows what the problem could be? "unrecognized_name" has no matches in this discussions search.
