Hello there,
Your site is currently connected to Jetpack and you can also check this here: https://jptools.wordpress.com/debug/?url=https://YOURSITENAME.com
Plus I’m not having any issue accessing your site via WordPress.com or enable/disable Jetpack features.
If you still see the error message at any place in your site, please check it from a different browser and also make sure that there is no extension on your browser that may create the block. Ad blocker is a good example.
If you give us permission, we can also log in to your site’s WP Admin via WordPress.com login to verify if the error message is also for us or only for you. If it is only for you then, the issue is from your browser.
