Hi there @pradz81, thanks for getting in touch. The likely reason you are seeing this error while trying to connect Site Kit is because your site publicly accessible or is in maintenance mode. This is explained further on our known limitations page in the site availability section.
If you don’t believe this is the reason, then I’d be happy to look at this in more detail. Please could you share your Site Health information. You can use this form to share privately if preferred. I can then check your setup to see if anything stands out as to why you’d be getting the above error.
As we didn’t receive a response I’ll mark this as resolved. Feel free to open a new support topic if you continue to encounter issues, or reopen this topic and we’d be happy to assist.
