Hi there, @ftafnad,
Thanks for reporting this; I don’t see the error you mentioned but I can see some connections error in Jetpack that might trigger the Boost problem.
I see a 500 error upon trying to connect Jetpack to your site. The first thing to try is to increase the memory available to WordPress:

If that doesn’t work, can you check your error logs to see what exactly is going wrong? Your host can help you find them if you need help.
Let me know what you turn up!
