Try capture xxq.pcap attached to 5767: Create a BitTorrent DHT dissector for wireshark
Does your Wireshark config see BT-uTP frames?

Thank you. The problem is with the Enable protocol interface.

In the current stable version (4.4.3) there is already an option to enable the bt_utp_udp dissector, disabled by default:

The protocol should be supported earlier versions, the problem is the startup protocol here, when entering different keywords when searching, the results are not the same.

The problem lies in the enabling protocol interface. When searching bt-utp, the secondary directory is not expanded, so bt_utp_udp is not selected. This will be confused when adding dht protocol, and I hope to improve it
