redirect_uri_mismatch the redirect URI in the request does not match the ones authorized for the OAuth client

I have following client secret

{"web": {"client_id": "testid","project_id": "testproj","auth_uri": "https://accounts.google.com/o/oauth2/auth","token_uri": "https://www.googleapis.com/oauth2/v3/token","auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs","client_secret": "test-sec","redirect_uris": ["https://localhost:8080/oauth2callback"    ]  }}

and I am getting

"Error: redirect_uri_mismatch The redirect URI in the request, http://127.0.0.1:8414/authorize/, does not match the ones authorized for the OAuth client.

To update the authorized redirect URIs, visit:". Could you please suggest, how to fix it.

I am using C#. I have created credentials with this -

GoogleWebAuthorizationBroker.AuthorizeAsync( GoogleClientSecrets.Load(stream).Secrets, scopes,"user",                                              CancellationToken.None,                                               new FileDataStore(Directory.GetCurrentDirectory() +"\\AccessToken\\" ,                                              true)).Result; 

But for first time , it popped up with login and once I logged in , it has created Google.Apis.Auth.OAuth2.Responses.TokenResponse-user file in the folder. Is there a way to bypass first time login ?

Thanks.
