Error Details: Jetpack ID is empty.

Hmm, two months gone, but no solution for that problem..
I’m next one with that issue. I installed Jetpack thru WordPress administration (no problem with it) and when i klick to “connect to wordpress.com” buton, i get error message jetpack_id (Error Details: Jetpack ID is empty. Do not publicly post this error message!).
After that i installed also test utility that you suggested in other post. Result of that is:
