Error Message “Jetpack.json API Does Not Exist”

I am having issues relaunching my website, golfattheoaks.com, after my WordPress plan expired. I renewed it once I realized this, and used the Jetpack tool to recover a backup of the website before it went down. I had no issues reloading the saved file, and I am ready to relaunch it.

I am now getting the error message when I try to launch it that “The Jetpack site is inaccessible or returned an error: server error. Requested method jetpack.jsonAPI does not exist. [-32601] I also am seeing an error message on my WordPress dashboard that Jetpack is not connected to my site. I am not sure where to go from here.
