Snapshot breaks Jetpack "Jetpack could not contact register_http_request_failed&

When I installed Snapshot, I could not longer access the plugins directory, jetpack or install any more WPMUDEV plugins or themes. Jetpack gave this error:
Jetpack could not contact register_http_request_failed
So I deactivated all plugins and slowly reactivated until the error started happening again. It was the Snapshot plugin. As long as it is deactivated, my site works fine.
