Unknown Error after fresh Install

Hi Everyone,

I did not find anything fitting, so I’m trying a new post. I have installed the server before and got an -8 Error in the ConversionService and all of the suggestions did not resolve this. So I thought a fresh start would be good.

The Installation and Switch to https was no issue, but as soon as I Switched, the service does not work anymore. If I try to connect the Nextcloud App, I get the following Error:

[onlyoffice] Fehler: Exception: Im Dokumentenservice ist ein Fehler aufgetreten: Unknown error at <>

If I start the example server, i get the following Error:

Let’s take a look at what happened. :handshake:

  1. Please open local.json in
    For Linux - /etc/onlyoffice/documentserver/local.json
    For Windows - %ProgramFiles%\ONLYOFFICE\DocumentServer\config\local.json

and find section below:

     "token": {
        "enable": {
          "request": {
            "inbox": true,
            "outbox": true
          "browser": true
        "inbox": {
          "header": "AuthorizationJWT"
        "outbox": {
          "header": "AuthorizationJWT"
      "secret": {
        "inbox": {
          "string": "your_secret"
        "outbox": {
          "string": "your_secret"
        "session": {
          "string": "your_secret"

Compare values of JWT token secret and header from both configuration files, these values should match. If they do not match, please replace the values in local.json with the required ones and restart all services of Document Server

  • via Windows Services

  • For RPM/DEB packages:
    systemctl restart ds-*

  • For Docker:
    supervisorctl restart all

  1. If the problem persists, please provide access to the logs (/var/log/onlyoffice/documentserver/docservice/out.log) and the local.json file ."

  2. Perhaps I will be able to reproduce the issue. Could you provide a detailed scenario with links to the guides?
