We are starting the process of migrating our site to Sitefinity. I created some layouts locally and deployed to our test environment. When I hit the site (as a user), I am returned the home page without issue. When trying to sign in to the back end, I am receiving the log in page. After I type in credentials and hit Login, I receive a 302 from /Sitefinity/Authenticate/SWT and then a 504 from /Sitefinity/dashboard (which has a long querystring of wrap_deflated, wrap_access_token, etc). I believe this might have to do with our load balancer but I am not sure and don't know what I need to do (even after reviewing multiple threads and documentation on the subject). Can anyone help me? Thank you.
One additional thing I just noticed is that we hit our test URLs with https (which is then forwarded from the load balancer to the server as http). When I am on page /Sitefinity/Authenticate/SWT on testing, the querystring has a realm= value of http://(oursite) vice https. Not sure if that matters.
