Wifi Connect not displaying login credentials page on Raspberry Pi 3B+ (on-board wifi)

[rscottcarson]

I am setting up Wifi Connect on a Raspberry Pi 3B+ as part of our docker image.

We are successfully able to start wifi-connect (we can tell by the logs and the AP is active). However, when we connect to the Wifi Connect network on a mobile device, the "Sign in to network" notification shows, but when it is pressed we are brought to a blank page instead of the login credentials portal. If the user attempts to navigate to a webpage (i.e. www.google.com), we are not redirected to the login credentials portal either. It seems as though the webpage is not being served properly, or we have simply misconfigured something.

I have included our Dockerfile.template and start.sh script below:

Closed due to problem being solved. Documentation should emphasize that wifi-connect must be run from it's own directory.
