Answer 1

Have you tried setting secure: always in your handlers in your app.yaml?

handlers:
- url: /youraccount/.*
  script: accounts.app
  login: required
  secure: always

always

Requests for a URL that match this handler that do not use HTTPS are automatically redirected to the HTTPS URL with the same path. Query parameters are preserved for the redirect
