Unable to create room

Hello,

I am using Photon Real Time in Unity 3D (Not PUN) and everything worked great for a very long time. Lately I find myself unable to join a room I have created (no changes were made to the code).

When the client state changes to "JoinedLobby" I am calling LoadBalancingClient.OpJoinOrCreateRoom(EnterRoomParams opParams) like this:

 public void JoinOrCreateRoom(string roomName, byte maxPlayers, int playerTtl, int emptyRoomTtl)
    {
        try
        {
            if (this.State == ExitGames.Client.Photon.LoadBalancing.ClientState.JoinedLobby)
            {
                ExitGames.Client.Photon.LoadBalancing.RoomOptions roomOptions = new ExitGames.Client.Photon.LoadBalancing.RoomOptions()
                {
                    MaxPlayers = maxPlayers,
                    PlayerTtl = playerTtl,
                    EmptyRoomTtl = emptyRoomTtl,
                    CheckUserOnJoin = true,
                    IsOpen = true,
                    IsVisible = true,
                    CleanupCacheOnLeave = false
                };
                OpJoinOrCreateRoom(roomName, roomOptions, ExitGames.Client.Photon.LoadBalancing.TypedLobby.Default);
            }
            else throw new Exception("Not in lobby.");
        }
        catch (Exception exception)
        {
            Debug.LogError(exception.Message);
            throw exception;
        }
    }

There are no visible errors but the client changes to the states -
1. Joining
then
2. DisconnectingFromMasterserver
then
3. ConnectingToGameserver

and gets stuck there.

What could be the problem?

I tried printing the OperationResponses and Events but I cannot understand them.
The OperationResponse I get is "OperationResponse 229: ReturnCode: 0 (). Parameters: {}" and the event I get is "Event 230: {(Byte)222=(Hashtable){}}"

Please assist.
