After setting up an app in the google app engine with a domain name, I found that accessing the domain via the naked domain name (no www.) would not work.
Worked:
http://www.mydomain.com
Didn’t work:
http://mydomain.com
After search for a while, I came across this answer:

The solution is to forward mydomain.com to www.mydomain.com with your domain registrar. After doing this, it worked as expected.
