Mautic Error 400

Hi, I am trying to link my mautic installation with the wordpress website.

The error is shown when I enter the URI and keys –

{“errors”:[{“message”:”The redirect URI provided does not match registered URI(s).”,”code”:400,”type”:”redirect_uri_mismatch”}],”error”:”redirect_uri_mismatch”,”error_description”:”The redirect URI provided does not match registered URI(s). (error and error_description are deprecated as of 2.6.0 and will be removed in 3.0. Use the errors array instead.)”}

The page I need help with: [log in to see the link]
