Can you please re-open question 12693 titled “OpenID Connect - redirect_uri http vs https”
It says new users cant post links even tho im simply trying to link to this exact devforum 
The answer to the posters question is “You have to configure flask to set the wsgi.url_scheme to https so url_for will return https URLs”
See Stack overflow question 14810795 “flask-url-for-generating-http-url-instead-of-https”
The answer to “how are you supposed to find that out” is
“thru reverse engineering the flask-oidc and authlib source code”
It doesn’t appear to be documented anywhere…
