Hello @bigAboo
Please reproduce the issue > make screenshot of the error > provide us with whole Document server logs folder. It’s located here: /app/onlyoffice/DocumentServer/logs/documentserver/
Also please point us to the guide which you used for Document server installation.

Hello ) Thank you for your response.

Here is my Docker-compose part for onlyoffice Doc Server

  onlyoffice:
    container_name: onlyoffice
    depends_on:
      - mariadb
      - onlyoffice-rabbitmq
    environment:
      - DB_TYPE=mysql

      - DB_PORT=3306
      - DB_NAME=onlyoffice
      - DB_USER=onlyoffice
      - DB_PWD=$ONLY_OFFICE_MYSQL
      - AMQP_URI=amqp://guest:guest@onlyoffice-rabbitmq
      - JWT_ENABLED=true
      - JWT_SECRET=$JWT_SECRET
      - JWT_HEADER=Authorization
      - JWT_IN_BODY=true
    image: onlyoffice/documentserver:latest
    networks:
      - t2_proxy
    stdin_open: true
    tty: true
    restart: always
    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=t2_proxy"
      ## HTTP Routers
      - "traefik.http.routers.onlyoffice-rtr.entrypoints=https"
      - "traefik.http.routers.onlyoffice-rtr.rule=Host(`onlyoffice.$DOMAINNAME`)"
      - "traefik.http.routers.onlyoffice-rtr.tls=true"
      - "traefik.http.routers.onlyoffice-rtr.middlewares=onlyoffice-headers"
      - "traefik.http.middlewares.onlyoffice-headers.headers.customrequestheaders.X-Forwarded-Proto=https"
      - "traefik.http.middlewares.onlyoffice-headers.headers.accesscontrolalloworiginlist=*"
      ## HTTP Services
      - "traefik.http.routers.onlyoffice-rtr.service=onlyoffice-svc"
      - "traefik.http.services.onlyoffice-svc.loadbalancer.server.port=80"
    volumes:
      - $DOCKERDIR/onlyoffice/document_data:/var/www/onlyoffice/Data
      - $DOCKERDIR/onlyoffice/document_log:/var/log/onlyoffice

  onlyoffice-rabbitmq:
      container_name: onlyoffice-rabbitmq
      image: rabbitmq
      networks:
      - t2_proxy
      restart: always
      expose:
        - '5672'

As you can see DC logs are in $DOCKERDIR/onlyoffice/document_log

There i saw /documentserver folder, where err.log file is empty, out.log contains:

These are old entries. If it’s possible please provide us with whole logs folder.
A few more things. Please check mutual availability between servers. For example, go to Nextcloud host and run wget https://DS_domain name. And vice versa - from DS host run wget https://Nextcloud_domain name.
Please show us the result.

Also please let us know if Document server is installed on separate server.
