As always it turns out that I’m an idiot. I had some upper-case letters in my domain (forum.HappyCoding.io
). Modifying the app.yml
file to only user lower-case letters (forum.happycoding.io
) solved the problem.
I noticed this when I looked at the output for disocurse-doctor
, so thanks very much!
Btw, I found a similar thread with a similar problem here.
