Nope, sorta normal. The unauthorized always happens when you hit the web page for the first time — that’s what let’s the browser know it should log on. The moved means you went to http://ip.address:3689, and not http://ip.address:3689/, so it pushed you to the right place.
Mostly normal. Probably log levels on those should be turned down, but I do want to log *real* http errors, so I guess I’m just used to ignoring those. 🙂
