What is the problem?

When the packet loss of μTP, it will not actively use BT, resulting in 0 speed

When two qbit clients connect, using the default options, there will be a momentary connection to μTP (UDP), and then the connection will be lost due to network environment reasons

The option μTP-TCP mixed mode algorithm (mixed_mode_algorithmqbit) = Perfer TCP does not actively use BT (TCP)

If TCP is turned off in the settings（Peer connection protocol = TCP）, It can be successfully connected and the speed can reach the upper limit of broadband

Steps to reproduce

1. Default option:
   μTP-TCP mixed mode algorithm (mixed_mode_algorithmqbit) = Perfer TCP
Peer connection protocol = TCP and μTP
2. Two qbittorrent clients
   Sender: Seeding
   Receiver: Downloading (For connection stability, add peer: Sender's [IPv6]:port)
