"Redirecting you back to the application" never finishes redirecting

Hi all,

For some reason, when I host my application on AWS or Heroku, the “Sign in with Twitter” button never redirects back to my webpage. This is strange, because it DOES redirect when I run the website in localhost. In other words, everything works fine when I deploy the WAR file in localhost, but the application messes up by not redirecting on AWS. To see the error, see my application: http://sample-env.vzqeyzumtm.us-west-2.elasticbeanstalk.com/

I am using Twitter4j with a Tomcat server.

Can anyone help? Thanks.

It’s correctly redirecting back to your application which is then throwing an error. Check your Lambda logs/configuration.

This is where it redirect to and the error response.

You were right, thanks. The problem wasn’t that it wasn’t redirecting. Rather, the problem was that there was an exception when I tried to write the user’s credentials to my DB. Solved.
