docker: "first record does not look like a TLS handshake" error when pull image

I have just installed docker and then try running hello-worldprogram. My server is behind proxy of company. So, I set proxy environment variables according to manual from docker in a file named /etc/systemd/system/docker.service.d/http-proxy.conf:

[Service] Environment="HTTP_PROXY=" Environment="HTTPS_PROXY=" Environment="NO_PROXY=localhost,127.0.0.1,localaddress,.localdomain.com" 

But, while run $ sudo docker run hello-world. I get the error

Unable to find image 'hello-world:latest' locally docker: Error response from daemon: Get proxyconnect tcp: tls: first record does not look like a TLS handshake. See 'docker run --help'. 

This is docker version:

Can anyone help me ? Thank All !!!

I had this exact issue and it was due to HTTPS_PROXY not having the correct variable (https instead of http) assigned to it in both bashrc and docker desktop settings configuration
