El orden de los tipos MIME en la cabecera de solicitud accept enviada al servidor Discourse parece importar:
curl -i -H 'Accept: text/plain, text/html' https://meta.discourse.org
HTTP/2 404
...
curl -i -H 'Accept: text/html, text/plain' https://meta.discourse.org
HTTP/2 200
...
Esto afectaría principalmente a los consumidores de la API, supongo. Abierto a una PR que corrija esto.
Probé esto en la compilación de desarrollo, estoy recibiendo 200 OK de Rails::WelcomeController#index para ambos encabezados Accept: text/html, text/plain y Accept: text/plain, text/html.

@sam ¿puedes por favor dar alguna indicación sobre cómo solucionar esto?
Esto no va a ser fácil de depurar, puede estar relacionado con la configuración de NGINX en producción, tal vez sea en Rails, no estoy seguro.
Intentaría primero hacer la solicitud directamente al proceso de Rails y no al proxy express, si eso funciona, entonces depuraría una configuración de docker de producción de forma local.
Sí, enviar las solicitudes directamente al proceso de Rails tampoco reproduce el problema
