Mistral doesn't use oslo_middleware.http_proxy_to_wsgi.

If the passing of the forward headers (X-Forwarded-For, Host, X-Forwarded-Proto, X-Forwarded-Prefix) is enabled in https terminating proxy and proxy headers parsing is enabled in oslo_middleware, Mistral doesn't use this middleware.

mistral.conf
[oslo_middleware]
enable_proxy_headers_parsing=True

curl https://api.example.com/workflowv2
