I'm getting the same thing. I wasn't 100% sure I had it correct, but since other, similar URLs issue a 404 this makes me think we got the URL correct. Either I am not seeing how this relates, or they are having issues.

for me, I changed https -> http and it worked.

I just tried that, but still get redirected back to https. I even tried using curl and I get a 302.

Got the same problem from chapter 8 -> 9...

I got this as well, but refreshing will fix it.

If you're on that page, you've got the right answer. The wrong one will give you a 404 error instead.

Just keep refreshing.

Thanks for the tip, I'll try that.

Are people brute-forcing the 5 letter password? ;)

It seems like that would be a lot more work than just figuring it out the right way..

Keep refreshing and you'll get the right page.

I just tried again, and it worked.
