UDP Port bind() failed & net.bind_ip


Recommended Posts

I spent a lot of time looking for this and I didn't find anything online that answered the question for me. Now that I have found it I will share it with you.


"UDP Port bind() failed" in the logger

Red Light in the Network Status (http://www.utorrent.com/faq.php#What_do_the_Network_Status_lights_mean.3F)

Check to see if net.bind_ip is set. If it is set, then either make sure that the value is the IP assigned to your computer, or Reset the value to its default of blank. Unless you have an advanced network setup, it is recommended to reset the value to its default.


Normally the net.bind_ip option allows you to specify which network adapter uTorrent should use to listen for incoming connections. This is useful if you have multiple network interfaces. When this option is used, uTorrent will look for a network adapter that has the provided IP address. If no matching adapter is found, then uTorrent will be unable to bind (listen for connections). Generally to have this problem, the net.bind_ip option must have been set previously. Once the option is set, and the adapter is removed, disabled, or changes IP addresses, then the symptoms will appear.

Hope this helps someone else.
