It's great, how it redirects and redirects non-stop. When all I did was run one command: gcloud app deploy

I'm experiencing the same behavior with XF 2.2.11

Maybe THAT's why?
XenForo is NOT designed as a "deployable app", which that command appears to expect to be in place. It looks like it expects to see a YAML to install?
The other question I have... why?
