[Nextcloud] Restrict access to your ONLYOFFICE Document Service to the users of your Nextcloud instance

Enable JWT token

Add a Token in you local.json file. If your running ONLYOFFICE on linux you will find the file here:

/etc/onlyoffice/documentserver/local.json

Set inbox, outbox and browser to true and add you token in the secret part for inbox, outbox and session. I just generated a random string via Bitwarden.

   "token": {
        "enable": {
          "request": {
            "inbox": true,
            "outbox": true
          },
          "browser": true
        },
        "inbox": {
          "header": "Authorization"
        },
        "outbox": {
          "header": "Authorization"
        }
      },
      "secret": {
        "inbox": {
          "string": "token_string"
        },
        "outbox": {
          "string": "token_string"
        },
        "session": {
          "string": "token_string"
        }

Save the file and run:

supervisorctl restart all

Go to your Nextcloud web interface, open your ONLYOFFICE App and add your token beneath your server url.

Configure IP Filter

Search in the following file for “ipfilter”:

/etc/onlyoffice/documentserver/default.json

Add you domain or IP to the IP rules. Disallow everything else. Use * as wildcard. Also set useforrequest to true.

"ipfilter": {
              "rules": [{"address": "url_or_ip", "allowed": true},
                        {"address": "*",         "allowed": false}],
              "useforrequest": true,
              "errorcode": 403
            },

Now run again:

supervisorctl restart all

And test if the service is reachable.
