I've set up a vanity URL shortener at caa.to. Using DNSimple for my DNS, browsing to caa.to appropriately lands me at www.caa.to and the associate Pythonanywhere associated site. However, when use a shortened URL such as caa.to/7, I get the error message in the subject. Note that www.caa.to/7 does work as designed. DNS configuration issues? Suggestions would be greatly appreciated.
