@holyjack I've tried several times, and on two separate machines. I still get the "Page not found" error. I'm including the exact commands I used. Perhaps you can see what I am doing differently.

And, here is a screenshot of the browser.

Any idea where I can look next to find the issue?

Another approach. Since the current state of the repo is broken, how about just applying your pull request and seeing what happens in CI. Thoughts?

@U0522TWDA I think I have found the problems. What I did was to compare what you have with what is created by lein new cryogen I am attaching a patch file for src/cryogen/server.clj that you can apply to your server.clj. With this patch, I can get lein ring server to work. If you apply this patch to your fork and let me know, I'll try out the updated fork.
