Не получается в NGINX принять POST запрос в формате JSON

Мучаюсь уже много времени с проблемой приема POST запроса на nginx , на локальном сервере все работает замечательно .на vps только GET работает уже прописал и заголовки и тд .но продвижения нет от слова совсем ,может есть какие то наработки по этому вопросу вот конфиг nginx

listen 80;
listen 443 ssl http2;
server_name www.mydomain.ru mydomain.ru;


root /home/admin/web-app/arigato-app/dist/;
