1. Disable IPv6 (if applicable)
2. Reset Winsock
3. Whitelist, Allow uTorrent and Incoming Ports
4. Uninstall third-party security software

Let’s take a look at the description of the process involved concerning each of the listed solutions.

1] Disable IPv6 (if applicable)

You can begin troubleshooting to fix the uTorrent Connection Error 10047 that occurred on your Windows 11/10 computer by disabling IPv6. Try the next solution if this didn’t work for you.

2] Reset Winsock

You are likely to encounter this particular issue due to some type of network inconsistency that’s either facilitated by bad TCP or IP data that ends up affecting the stability of your Internet connection. In this case, to fix the error in view, you can reset Winsock and for good measure, you can flush DNS, reset proxy, release TCP/IP on your Windows 11/10 PC and see if that helps.

3] Whitelist, Allow uTorrent and Incoming Ports

This error may occur because your antivirus and firewall are blocking the incoming connections. So, to resolve the issue, if you have a third-party security software or dedicated firewall running on your system, to whitelist and allow uTorrent and incoming ports, you’ll need to refer to the security software user-manual.

On Windows 11/10, you can whitelist uTorrent application, allow uTorrent app in Windows firewall and can allow uTorrent incoming connection port in Windows Firewall. But, to allow the uTorrent incoming port on either the third-party firewall or Windows firewall, you need to first identify which port is currently used by the peer-to-peer client for your incoming connection on your device. Do the following:

• Open uTorrent.
• Click on Options from the ribbon menu at the top.
• Click on Preferences from the context menu.
• On the Preferences menu, click on the Connections tab from the menu on the left.
• Now, on the right-hand side, make a note of the Listening Port that is actively being used for incoming connections.

Proceed with the next solution if after carrying out these tasks the issue in hand is still unresolved.

4] Uninstall third-party security software

You are most likely to encounter this issue if you have third-party firewall and antivirus installed and running on your Windows 11/10 system. So, if whitelisting and allowing uTorrent and incoming connection ports on the installed security software didn’t fix the error for you, you will have to remove all third-party antivirus programs from your PC using the dedicated AV removal tool to remove all files associated with your antivirus program and switch to Windows native AV program – Windows Defender.
