# Truebleshooting

### 1. Node Not Starting

**Symptom**: Container exits immediately or logs show errors.

**Checks**:

* **Private Key**: Ensure `PRIVATE_KEY` starts with `0x`.
* **Ports**: Check if port `8000` (or your configured port) is already in use.
* **Database**: Ensure Typesense or the database container is running.

**View Logs (Docker)**:

```bash
docker logs ocean-node
```

**View Logs (PM2)**:

```bash
pm2 logs ocean-node
```

### 2. "Database Retrieve Error"

If you see errors related to retrieving data from the database:

* Ensure the database container (`typesense` or `elasticsearch`) is healthy.
* Check network connectivity between the Node container and the Database container.

### 3. GPU Not Detected

If your node is not picking up your GPU for compute jobs:

* Ensure you have the correct drivers installed (NVIDIA drivers, CUDA).
* If running in Docker, ensure you have the **NVIDIA Container Toolkit** installed so Docker can access the GPU.
* Check `DOCKER_COMPUTE_ENVIRONMENTS` in your config to see if it was manually overridden.

### 4. Rate Limits

If you see errors related to Docker Hub rate limits:

* This happens when pulling too many images.
* **Solution**: Authenticate with Docker Hub (`docker login`) or upgrade your Docker Hub plan.

### Where to Get Help

* **Discord**: Join the Ocean Protocol Discord `dev-support` channel.
* **GitHub**: Open an issue in the [ocean-node repository](https://github.com/oceanprotocol/ocean-node/issues).
