With Jetpack, your stats information is connected to a unique blog ID. Sometimes, if you were using a development site or a different address when you set up Jetpack, disconnecting may create a new blog ID. When this happens, it may appear that your stats and subscribers were lost.
That’s what happened on your site: you were using a temporary site address (188.8.131.52/~acubienc/) when you set up Jetpack, and this URL was not updated in Jetpack when you updated your site URL.
I have fixed the issue for you, and you should get your stats and subscribers back by going to the Jetpack menu, and disconnecting / reconnecting to WordPress.com.
