If your Chrome browser has a problem, the GameStream Error Code 47439999 might reflect.

Corrupt cache stored in the corresponding NVIDIA Experience folder usually offsets GameStream. Clearing the cache and cookies will help solve the problem. Here’s how:

  8. Start the operation by selecting Clear data.
  9. Wait for the procedure to complete, and then restart the computer.

Solution #2: Forward Ports Utilized by GameStream

Blocked ports can be the cause of the error. Your firewall or router can be the one blocking the forwarding of these ports. The first approach is to enable the Universal Plug and Play feature on your router. The steps to do so come from the manufacturer of your router and they differ depending on the brand. Regardless, you should be able to enable UPnP from the Settings menu, then access the Advanced tab.

If your router does not support UPnP, don’t despair. You can manually forward the used ports. Follow the instructions below if you don’t know how to forward the required ports.

  1. Open your browser and go to the following address:
    192.168.0.1 or 192.168.1.1
  2. Login to your router by inserting your admin credentials. These are underneath your router or in a separate sheet provided by the distributor.
    Note: If you changed the default login credentials, you can reset the browser back to its original state.
  3. Once you have gained access, go to the Advanced menu. Expand it to reveal a section titled NAT Forwarding or Port Forwarding.
  4. Now, check for the feature that lets you add ports to the list.
  5. Forward the following ports:
    47998 UDP
    47999 UDP
    48000 UDP
    48010 UDP

The solution may seem weird but it works anyhow. To fix the issue, access the Task Manager. Then find all services related to NVIDIA before launching the GameStream feature. The problem likely stems from a corrupt NVIDIA Experience service.

  2. Now, go to the Services tab and select the Description column.
  3. Find all NVIDIA services and right-click on each. Select Stop from the context menu. Make sure you repeat the same process on all NVIDIA services that are running.

Solution #4: Get a VPN

As already indicated, the error code 47439999 with GameStream can occur due to a shared IPv4 clashing with the NVIDIA share functionality.
