    I am using wireguard. Wireguard uses udp, and the port of wireguard is 443. When I stopped wireguard, docker execution succeeded.

    I wonder why wireguard didn't show up when I used sudo netstat -nlutp | grep 443.

    Please kill all process that use port 443:

    for i in $(lsof -i -P -n  | grep 443 | awk '{print $2}'); do kill -9 $i ; done

    then run your container again

    sudo docker run -d -it -p 443:443 -p 443:443/udp --name nginxx nginxx
