I had been facing the same issue, eventually i fixed it by adding the following callbacks,
http://127.0.0.1:3000/auth/twitter/callback http://127.0.0.1/ http://127.0.0.1/auth/twitter/callback http://localhost:3000/auth/twitter/callback
and it worked like a charm, [![enter image description here][1]][1]
