проверил Access-Control-Allow-Methods
- проблема сохранилась nginx разрешает заливать в себя сколько влезет....

BitKinex - послал PROPFIND
nginx - ответил Access-Control-Allow-Methods: GET
BitKinex - игнорировал хидер и инициировал PUT
nginx - разрешил PUT и получил файл....
[lua] блокировал его размещение HTTP/1.1 405 Not Allowed
:(
