Thanks for opening a support topic @sibichan. Based on reviewing your site and your Site Health information, we’ll need to perform some checks to determine why you’re unable to set up the plugin. In order to do so, please share the following:

1. Do you see any warnings or errors when checking yourSite Health status? (Tools > Site Health > Status), which differs from your Site Health information shared previously? Such errors may include REST endpoint references.
2. What is your current location? I ask as Google services are blocked in some regions, and this can be one such reason for the final error you reported.
3. Have you been able to set up Site Kit on this site previously, or on any other site on the same hosting platform?

Let me know if you have any questions with the above.

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.
