# Troubleshoot EdgePointDown Message

## 🧠 Understanding the Issue

The `EdgePointDown` status typically indicates a failure in establishing communication between your node and the network’s edge points.

A known root cause is the system **resolving outbound connections using IPv6 instead of IPv4**, which can happen in scenarios such as:

* The cloud provider defaults to IPv6 or uses IPv6-to-IPv4 translation
* The network infrastructure between your VPS and Constellation’s edge points mishandles IPv6
* DNS resolution or routing forces IPv6 where IPv4 is required for compatibility

{% hint style="warning" %}
⚠️ This guide addresses **IPv6-related causes only**. 

As new root causes are discovered, this document will be updated.
{% endhint %}

### Backup Your `.p12` Keystore

{% hint style="danger" %}
⚠️ **Important:** 

This procedure modifies your VPS’s system configuration. If a misstep occurs, you may lose node connectivity.
{% endhint %}
{% endstep %}

{% step %}

### Confirm Your `nodectl` Version

You must be running **`nodectl` v2.15.2 or later**:

```bash
sudo nodectl version
```

{% endstep %}

{% step %}

### Check IPv6 Status

```bash
sudo nodectl ipv6 status
```

Expected output:

```
--------- * IPV6 STATUS * ---------
Interface found ................... eth0

IPv6 sysctl Status   IPv6 GRUB Status
enabled              enabled
```

If you find `IPv6` is disabled, you do not need to continue this troubleshooting guide. Please contact an administrator.
{% endstep %}

{% step %}

### Disable IPv6 with sysctl

To restrict the system to use IPv4-only routing:

```bash
sudo nodectl ipv6 disable --ni --sysctl
```

This updates the system configuration to disable IPv6 via `sysctl`.

{% hint style="danger" %}
⚠️ If **either** status is already `disabled`, your issue is **not IPv6-related**.\
Stop here and seek assistance from a Team Lead via the [Constellation Network Official Discord](https://discord.gg/constellation).
{% endhint %}
{% endstep %}
{% endstepper %}

### Check IPv6 Status

> ⚠️ If **either** status is already `disabled`, your issue is **not IPv6-related**.\

***

## Restart Auto Restart (Optional)

To ensure the monitoring service is in sync with the updated configuration:

```bash
sudo nodectl auto_restart restart
```

***

## Conclusion

✅ **Your node should now resume connection attempts using IPv4**. 

If the `EdgePointDown` issue was caused by IPv6, it should be resolved.

If problems persist, please reach out to the Constellation Network support team or a Team Lead in Discord.
