Hello,
I apologize for the issue you are facing while trying to connect. If you are unable to connect using the regular method, you can try the manual connect method. Unfortunately, the manual connection process is not detailed in the provided context. To assist you further, could you please provide more details or screenshots of the options available in the settings related to manual connection?
Thank you for your understanding.

Hello,
For troubleshooting, you can skip the Google connection process in the Setup Wizard.
Then, please verify using the URL prefix and ensure that you have verified the correct version of your website on the Google Search Console (HTTP or HTTPS, www or non-www).

You can follow our guide here to create the URL Prefix property:

The URL-prefix property also helps keep your sitemap in sync with Google Search Console as we submit it automatically for you. In addition, the domain property won’t work correctly on some sections of the Analytics module such as the IndexStatus.
Hope that helps.
