i forgot docker and now it is good:

cat <> /etc/systemd/system/docker.service.d/proxy.conf
[Service]
Environment="HTTP_PROXY=http://proxy.someplace.com:8080/" "HTTPS_PROXY=http://proxy.someplace.com:8080/" "NO_PROXY=127.0.0.1,localhost,.someplace.com"
EOT

systemctl daemon-reload && systemctl restart docker && exit
