Fix uTorrent connection error 10047

If you have met the UTorrent connection error 10047 on your Windows 11/10 computer, you can try our recommended solutions below in no particular order and see if that helps resolve the issue.

  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 regarding each of the solutions listed.

1]Disable IPv6 (if applicable)

Disable IPv6

You can start troubleshooting to correct the UTorrent connection error 10047 that happened on your Windows 11/10 computer by disabling IPv6. Try the next solution if it doesn’t work for you.

2]Reset Winsock

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

3]White list, allow uTorrent and incoming ports

Allow incoming connection port — Windows Firewall

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

In Windows 11/10, you can whitelist uTorrent app, allow uTorrent app in Windows firewall, and allow uTorrent incoming connection port in Windows firewall. But, to allow the uTorrent inbound port on the third party firewall or Windows firewall, you must first identify which port is currently used by the peer-to-peer client for your inbound connection on your device. Proceed as follows:

  • Open uTorrent.
  • Click on Options in the ribbon menu at the top.
  • Click on Preferences from the context menu.
  • On the Preferences menu, click on the Connections tab in the left menu.
  • Now on the right side note the Listen Harbor which is actively used for inbound connections.

Continue to the next solution if, after performing these tasks, the current issue is still not resolved.

4]Uninstall third-party security software

You are more likely to experience this issue if you have a third-party firewall and anti-virus software installed and running on your Windows 11/10 system. So if whitelisting and allowing uTorrent and inbound connection ports on installed security software did not fix the error for you, you will need 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.

Hope this helps you!
