Goo.gl shortener not working here

Hi there,

First, thank you for your work. Since OwnCloud 5 we don't have a shortening service (Shorty does not work for me, or it seems very complex to configure).

I saw I could set goo.gl shortening service. I'm not a big fan of Google, but I want to shorten my urls desperately...

Well, I set up my API key on google's developers console, and pasted on the OC Administration shorten section, where I previously selected goo.gl service as shorten service.

Now, when I click share on a file or folder, my typical URL appears (i.e.: http://myhostname/public/service/files/blahblah....). Note I have a dynamic DNS service.

What I did in order to get the public API on Google's Dev Console was to create a browser key ( a server key asked for an IP, and the others were Android app or iOS app) and put in there: _malevolent.servebeer.com/_ (my no-ip host with the wildcards)

Error log says
