Failed to automatically register with Discourse ID

Looks like a HTTPS redirect error, but I believe I’m forcing https anywhere required:

Discourse ID register failed at step ‘/register’. Error: Request to ‘/register’ failed: 400
Error: {“errors”:[“You supplied invalid parameters to the request: Redirect URI must use HTTPS”],“error_type”:“invalid_parameters”}

I did read about a force https setting in the admin panel once you get into the console, but that’s a step past where I can currently get to.
