400 Bad Request

Hi,
Good afternoon.
In the wordpress, in the plugin when i try to log inn the account to the Linkedin the following appears me
“An error occured, the error reported by LinkedIn is: 401 The token used in the request has been revoked by the user”
and then
“Something went wrong, the error reported by LinkedIn is: 400 Bad Request {“error”:”invalid_request”,”error_description”:”Unable to retrieve access token: appid/redirect uri/code verifier does not match authorization code. Or authorization code expired. Or external member binding exists”}.
Please try again later or if the issue persists please visit the Help tab.”

Can you hel pe identifying which can be the problem?
Thanks for your work and for the plugin.
