Message

Failed to bind to the port specified in 'Fix UDP port' option in Preferences

Detail

This means that Hamachi couldn't start listening on the port you manually selected for it to listen on in Preferences > Detailed Configuration.

It is usually because you have another program already listening on this port, and Windows detected a conflict. You can only have one application listen on a specific port.

Resolution

  • Change the UDP port you configured for Hamachi to be something that is not already in use. You can verify what is in use via the command prompt, with the netstat -ab command.
  • Determine which program is using the desired port, and disable it.
