TL;DR

The development/test version of this application runs on free servers which shutdown after 30 minutes of non-use. Because of that, the application might take a minute before it even begins to be delivered to your browser.

The "Too Long" Part of "TL;DR"

The Concierge Web App uses three different servers:

The Heroku hosting services shut down after 30 minutes of not being used. So the first time you click on the link, the client server needs to boot up, which takes about 45 seconds. The first time you try to sign in, the database REST server needs to boot up, which also takes about 30 seconds.

Because of all that, your browser might time out, or get an "Application Error" from the server while waiting to start the application, or while trying to sign in. If that happens, just reload the page. The second time you try to sign in, the client server and database server will probably have started. (Yes, I know it's a pain, but they're FREE!)
