Thanks for reaching out @mrsmith11. If you’ve already tried the “Redo plugin setup” button, with the same occurring, please perform a plugin reset and share whether you’re then able to proceed with setup (Tools > Available Tools > Reset Site Kit).
Note that by resetting, you will need to connect all previously connected modules once more.
What I suspect happened in your case, rather than being a plugin related change, was something at Google service, web host or network level impacted your site credentials when communicating with the Site Kit service. By resetting you’ll reset those credentials.
Let me know if you have any questions with the above. We also have a guide on the plugin website in relation to this error which contains more details of this.
