Hi @sumitmehtain,
Thanks for reaching out, and sorry to hear you’ve been having trouble setting up the plugin. Based on the error you’re encountering, I assume you’ve already attempting using the “Retry” button to proceed with setup. If so, please attempt resetting the plugin before setting up once more (Tools > Available Tools > Reset Site Kit).
For more details on this error, see the related guide on the plugin website.

Let me know how you get on after attempting a reset. Note also that I checked your site and while I didn’t spot anything obvious that may have lead to this error we can perform some additional checks if the same occurs after a reset.
Thanks for your reply and after resetting it’s working now
Thanks you again
