# Troubleshooting Screen Share and Connection Issues

If you're unable to see screens in the Trading Room or experiencing frequent disconnections, follow these troubleshooting steps:

### Step 1: Run a Connectivity Test

Start by testing your connection from within the Trading Room:

1. Click the **menu** in the upper left corner

2. Select **Connectivity**

3. Run the test and review your results:

**Important:** UDP should be enabled for WebRTC. If UDP is blocked, VPNs, firewalls, or ad blockers may be preventing screen shares from displaying properly.

### Step 2: Common Solutions

Try these fixes to resolve connection issues:

**→ Disable your VPN** – VPNs can interfere with screen sharing protocols

**→ Switch to a mobile hotspot** – This helps determine if your network is the issue

**→Temporarily disable your firewall** – Test if this resolves the problem (remember to re-enable it afterward)

### Step 3: Configure Windows Firewall (If Needed)

If your firewall is blocking the connection, you'll need to create an outbound rule:

1. Open **Windows Defender Firewall**

2. Go to **Advanced Settings**

3. Select **Outbound Rules** → **New Rule**

4. Choose **UDP**

5. Select **Ports**

6. Enter port numbers: **3478, 1024-65000**

7. Add domain: **\*.protradingroom.com**

8. Choose **Allow connection**

**9. Save** your changes

## Step 4: Additional Troubleshooting

If issues persist, try:

→ Using a **different browser** (Chrome, Firefox, Edge, Safari)

→ Opening the Trading Room in an **incognito/private window**

→Connecting from a **different internet connection**
