Error 404 del desafío acme del proxy inverso de Nginx

Tengo un vhost que parece funcionar bien, excepto que cuando intento generar SSL sigo recibiendo errores. ¿Alguien puede ayudarme a detectar qué está mal, por favor? Gracias

    example.com: Domain could not be validated, error message: error type: urn:ietf:params:acme:error:unauthorized, error detail:
192.168.9.123: Invalid response from https://example.com/.well-known/acme-challenge/NOHITCjOoL1lpdh-Oh1pHUSnXvkSk00ksjBeVCWA2cY: 404

Configuración de nginx vhost:

upstream domain-default {
  zone domain-default 64k;
  server 172.31.7.1:9001;
  keepalive 2;
}

upstream domain-ws {
  zone domain-ws 64k;
  server 172.31.7.1:3012;
  keepalive 2;
}

El error en sí dice que el dominio ejemplo.com no se puede verificar, debe reemplazar ejemplo.com con su dominio. No olvide apuntar la dirección IP del servidor al nombre de dominio, ya estará hecho.
