# Troubleshooting

If you have some problem with your node and still offline on staking dashboard, you can do this way to make your node online.

### Open Port

{% hint style="danger" %}
Remember to use this command one by one to avoid some of this command not applied.
{% endhint %}

```
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow ssh
sudo ufw allow 22
sudo ufw allow 9151/tcp
sudo ufw enable
```

Now you can check if your port is open or not with this [link](https://www.yougetsignal.com/tools/open-ports/).

Put **Remote Address** with your **VPS IP** and **Port Number** 9151 to make sure if your node port is open.

### Send tBNB to Worker Account

Most likely you didn't read all the guide i provided and you didn't send the tBNB to your worker. If you confuse which one is worker account, you can find it when you generate [geth account](https://docs.strnan.top/testnet/installation#generate-ethereum-account-and-keystore) and then send some tBNB like 0.05 or 0.1 or it's up to you.
