Vienna is unable to open a new subscription

[riklar]

Hello,

I have a site which was subscribe to Vienna, but on 1.1.17 stopped receiving updated posts.
This site on Feedly or another RSS reader is opened up to the last post towards the end of January.
What prevents Vienna, the last version on my desktop to be updated correctly.
The website is here
http://drucker10.net/?p=3105

Any idea?

I will try to look in to this shortly.

Thanks!
