# Troubleshooting

## Connection Issues

If you are trying to connect to the Workers Debug Server from a Workers application running in LabVIEW, and you don't see the Workers application appear in the Workers Application Manager, then the Windows firewall has probably blocked the connection from occurring. 

{% hint style="info" %}
By default a Debug Client will try to connect to a Debug Server over the **localhost** (which corresponds to IP address **127.0.0.1**) on port **6892**.
{% endhint %}

For LabVIEW and the Workers Debug Server, both need to be able to communicate over either the Windows **Private** network or the Windows **Public** network.

You can check that both **Private** and **Public** networks are allowed to be accessed by the **Workers 5.0 - Debug Server.exe** application, by ticking these boxes within the Windows **Allowed apps** settings, as shown below.
