Jetpack enabled self hosted sites are not connecting to wordpress.com

Hi,

I have two self hosted blogs. They are all up to date in terms of wordpress and jetpack versions but when I go into wordpress.com and try to manage the sites, the stats show up, but there are errors when I try to access anything else. I would like to use the Mac App which is why I’d like this to be solved.
Thanks! 🙂

The blog I need help with is migueldavid.eu.
