Most certainly 403 is related to the JWT Token on the Community Server side. I would not recommend disabling JWT Token since it provides a security of your connection and prevents data from being fetched by unauthorized users.

To configure JWT Token on both sides please follow next instruction:

  1. Locate next config var/www/onlyoffice/WebStudio/web.appsettings.config in the Community Server container (use docker ps to see the list of currently running containers and docker exec -it <ID> bash where <ID> is the ID of the container to connect to it);
  2. In the web.appsettings.config locate next strings:
  <add key="files.docservice.secret" value="<your_secret>" />
  <add key="files.docservice.secret.header" value="<your_header>" />

and copy somewhere values <your_secret> and <your_header>.

  1. Connect to Document Server container and open next config /etc/onlyoffice/documentserver/local.json;
  2. In local.json find next section:
      "token": {
        "enable": {
          "request": {
            "inbox": true,
            "outbox": true
          },
          "browser": true
        },
        "inbox": {
          "header": "<your_header>",
          "inBody": false
        },
        "outbox": {
          "header": "<your_header>",
          "inBody": false
        }
      },
      "secret": {
        "inbox": {
          "string": "<your_secret>"
        },
        "outbox": {
          "string": "<your_secret>"
        },
        "session": {
          "string": "<your_secret>"

and set inbox, outbox and browser values to true as it shown above to make sure that JWT is enabled and paste <your_secret> and <your_header> from web.appsettings.config to the string and header strings according to the example above.

  1. Restart Document Server services with supervisorctl restart all to apply these changes and try editing documents again.

Basically, you have to make sure that <your_secret> and <your_header> are corresponding in both configs.

Let me know if you face any difficulties.
