I recently had problems with my site. I deleted deactivated plugin wp-stats which then fall into avalanche of errors, and weird loops and on and on)
I recovered my blog, and reinstalled Jetpack. It will show me that I need to connect to wordpress, but when I click connect it will show me just this
Your Jetpack has a glitch. Something went wrong that’s never supposed to happen. Guess you’re just lucky: jetpack_id
Try connecting again.

It is weird because there isn't even error code, so I couldn't find solution online, please advice
