Google Redirect Mismatch URI

Hi,

I am getting the below error. I have done the setup as per the instructions on Google Console.
Checked with the hosting provider as well.. Nothing came out of that.

400. That’s an error.

Error: redirect_uri_mismatch

The redirect URI in the request, https://www.pallavidesigns.com, does not match the ones authorized for the OAuth client.
