Web UI login redirects build page and login page


I am following the S&W tutorial on an AWS Linux ec2 and Docker. I can’t get the web UI passed the welcome screen.
When I paste the build link into the browser the correct screen loads for a split second and then redirects to -

This site can’t be reached refused to connect.

Why do the pages redirect? Is this from the concourse image? I have changed the
CONCOURSE_EXTERNAL_URL to the ec2 url - and the .flyrc file

Thanks -

Does that behavior happen in an incognito/private browser session with cache disabled?

It works!!!

Thanks for responding.
