HTTPS request fails in Docker &g

I was given a solution by the Docker community
OpenStack network seems to use lower MTU values and Docker does not infer the MTU settings from the host's network card since 1.10.
To run docker daemon with custom MTU settings, you can follow this blog post, that says:

$ cp /lib/systemd/system/docker.service /etc/systemd/system/docker.service

Edit a line in the new file to look like this:

ExecStart=/usr/bin/docker daemon -H fd:// –mtu=1454

MTU of 1454 is the value that seems to be common with OpenStack. You can look it up in your host using ifconfig.
Finally restart Docker:

$ sudo systemctl daemon-reload
$ sudo service docker restart
