Getting error message 32752 when creating a room


I'm working on a multiplayer game in Unity, using Photon PUN 2.39.

Starting with today, sometimes when I want to create a room the OnCreateRoomFailed callback is triggered with 32752 return code and the following message:

Cannot create new room: (32752) - System.IO.FileNotFoundException : Could not load file or assembly 'Newtonsoft.Json, Version=, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'. The system cannot find the file specified.

Stack Trace:

There was no recent update to the game (I tested even with a stable one-year-old version that is working for a while) so this error is appearing out of nowhere.

The code for creating a room is this:

private static readonly RoomOptions RoomOptions = new RoomOptions
    MaxPlayers = 20, CleanupCacheOnLeave = false, PlayerTtl = 0, IsVisible = true,
    CustomRoomPropertiesForLobby = new[] {Constants.MapNameProperty}

public void CreateRoom(string roomName)
    menuManager.SetInfoText("Creating a room...");

    PhotonNetwork.CreateRoom(roomName, RoomOptions);

I'm also using webhooks but they are all quite simple. For example, the server code (nodejs express) for the endpoint connected to PathCreate is something like this:'/createAction', (req, res) => {

    // save data about the room

    return res.json({
        ResponseCode: 0

and it's working for a year without a problem.

Disabling webhooks seems to solve the room creation problem.

What do you think is the problem and how can I solve it?

    This was a server-side issue which we fixed.

    When did you encounter this and on which region?

  • @Tobias I am facing the similar issue when creating a room on my local server, it is a self hosted server through server plugin.

  • Please ... be more specific. I would like to help but "similar issue" is just not explaining your case well. It could be a number of different issues.

    If it's really similar, then the fix mentioned above will help. In all other cases, debug, gather info and post your own thread with proper info.
