docker push to local registry does not work

[linuxbsdfreak]

docker push -f 192.168.33.19:5000/nginx

FATA[0004] Error response from daemon: v1 ping attempt failed with error: Get https://192.168.33.19:5000/v1/_ping: EOF. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add --insecure-registry 192.168.33.19:5000 to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/192.168.33.19:5000/ca.crt
