Request key server from ubuntu container get waiting forever for specific port 80

Hello,

I have created an ubuntu image in docker and run it but I have a very strange problem that is:

if I run below command, it keeps waiting forever.
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0xB1998361219BD9C9

but If I run other command by remove port 80, it run well.
apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xB1998361219BD9C9

I need to resolve it by not remove port 80 because the software I need install that specify port 80 in keyserver url
