The most common reason for this error is when a program tries to use an IP version (like IPv6) that isn’t supported or turned on for your computer. This often happens if IPv6 is disabled, but a program still tries to use it. In some cases, having “::1” (which is the IPv6 version of localhost) in your hosts file while IPv6 is off can also cause this error. In this article, we will discuss different ways to solve this error.
1. Perform a Winsock Reset
For most users, this error is linked to a temporary network problem caused by corrupted TCP or IP data. Resetting your network settings (Winsock Reset) often resolves these issues.
2. Whitelist uTorrent and Its Connection Port
If resetting Winsock didn’t work, your antivirus or firewall may be blocking uTorrent. Adding uTorrent (and its port) to your whitelist can fix this. This process is a bit different depending on whether you’re using third-party security software or Windows built-in protection. Use the relevant guide below:

The location of uTorrent’s main program file (typically C:\Users[YourName]\AppData\Roaming\uTorrent if you didn’t choose a custom folder).The port uTorrent uses for incoming connections.
To view hidden folders like AppData, open File Explorer, select the View tab, and check Hidden items. To find uTorrent’s port:
2.2. Whitelisting uTorrent and Port in Windows Defender / Firewall
If you use Windows Defender and Windows Firewall, follow these steps:
3. Uninstall Any Conflicting 3rd-Party Security Software
Many users report that security suites like certain antivirus or firewall programs caused the An address incompatible with the requested protocol was used. (10047) error during the bandwidth test in uTorrent. Some antivirus programs (like AVG and similar) may block these connections by default. If whitelisting doesn’t solve it, or you can’t find the right settings, try temporarily uninstalling the third-party software and using only Windows Defender.
4. Disable IPv6 on Your Network Adapter
Some users have fixed this error by turning off IPv6 on their network adapter. You can always re-enable it later if you need it.
