If you encounter issues during setup, use this troubleshooting guide to diagnose and resolve common problems.

## Common issues

**Test network connectivity**

Run the following command to verify the Oracle Database port is reachable from this host.

```bash
(timeout 3 bash -c '</dev/tcp/<YOUR_ENDPOINT>/<YOUR_PORT>' && echo "PORT OPEN - Network connection successful!") || echo "CONNECTION FAILED - Port closed or firewall blocking"
```

**Expected output:** `PORT OPEN - Network connection successful!`

**Test OTLP endpoint connectivity**

Run the following command to verify your host can reach the selected New Relic OTLP endpoint.

```bash
ENDPOINT="<YOUR_OTLP_ENDPOINT>"
HOST=$(echo "$ENDPOINT" | sed 's|https://||' | cut -d: -f1)
PORT=$(echo "$ENDPOINT" | awk -F: '{print $NF}')
(timeout 2 bash -c "</dev/tcp/$HOST/$PORT" && echo "✅ SUCCESS") || echo "❌ FAILED"
```

**Expected output:** `✅ SUCCESS`
