I tried to use Onlyoffice docker version without jwt enabled and all was perfect, but now i tried to use jwt and faced the problem: Error while downloading the document file to be converted.) (version 7.0.0.132), here my compose file:

version: '2'
services:
  nginx:
    image : nginx:stable
    container_name: nginx_onlyoffice
    restart: always
    volumes:
      - ./nginx/vhost.conf:/etc/nginx/conf.d/default.conf:ro
      - ./mycerts:/mycerts 
    ports:
      - 443:443
      - 80:80
    depends_on:
     - onlyoffice
    
  onlyoffice:
    image: onlyoffice/documentserver
    container_name: onlyoffice
    restart: always
    environment:
      - JWT_ENABLED=true
      - JWT_SECRET=mysecret
      - JWT_HEADER=jwtauth           

nginx configuration:

server {
    listen 80;
    location / {
        return 301
            https://$host$request_uri;
    }
}

server {
    listen 443 ssl;
    server_name servername;
    root /var/www/html;

    ssl_certificate      /mycerts/server.chained.crt;
    ssl_certificate_key  /mycerts/server.key;
    ssl_trusted_certificate /mycerts/server.ca-bundle;

    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://onlyoffice:80;
    }
