Android QuickBlox SDK Client is not, or no longer, connected

Trying to join a dialog from the dialog instance locally saved in a Room Database Model. And it gives me this error. However, works fine when I fetch the dialog from server.

    public QBChatDialog getDialogFromDialogModel(ChatDialogModel mChatDialogModel) {
    QBChatDialog mQBChatDialog = new QBChatDialog();
    mQBChatDialog.setRoomJid(mChatDialogModel.getRoomJid());
    mQBChatDialog.setRoomJid(mChatDialogModel.getRoomJid());
    mQBChatDialog.setDialogId(mChatDialogModel.getDialogId());
    mQBChatDialog.setName(mChatDialogModel.getName());
    List<Integer> occupants = new ArrayList<>();
    String[] arrayoccu = mChatDialogModel.getOccupantsIds().split(",");
    occupants.add(Integer.parseInt(arrayoccu[0]));
    occupants.add(Integer.parseInt(arrayoccu[1]));
    mQBChatDialog.setOccupantsIds(occupants);
    mQBChatDialog.setLastMessage(mChatDialogModel.getLastMessage());
    mQBChatDialog.setUnreadMessageCount(mChatDialogModel.getUnreadMessageCount());
    mQBChatDialog.setUserId(mChatDialogModel.getUserId());
    mQBChatDialog.setType(QBDialogType.GROUP);
    mQBChatDialog.setLastMessageDateSent(mChatDialogModel.getLastMessageDateSent());
    mQBChatDialog.setLastMessageUserId(mChatDialogModel.getLastMessageUserId());
    return mQBChatDialog;
}


qbChatDialog = qbChatHelper.getDialogFromDialogModel(dialogModel);
                DiscussionHistory discussionHistory = new DiscussionHistory();
                discussionHistory.setMaxStanzas(0);
                qbChatDialog.join(discussionHistory, dialogJoinedCallback);

Have to do this before joining the (locally retrieved) dialog...

qbChatDialog.initForChat(QBChatService.getInstance());
