cannot get network delay

my command:
sudo docker run -d -it -e EULA=TRUE -e VERSION=1.21.62.01 -p 19132:19132/udp -v ./mc-bedrock-data:/data itzg/minecraft-bedrock-server
then I can connect and create world, but ↓


Start by reproducing the reported `sudo docker run` command from the issue and inspect the attached image for the network-delay symptom. The payload names no repository file, test, or specific expected behavior, so first determine the affected server or container networking component. Done should mean the cause is identified and the reported delay is resolved or clearly documented.
