I need help with Docker

hey guys, so actually today I'm having some troubles, I'm trying to install docker and have a go at it with a full stack app, but installing its not the problem.

me problem is when I try to do anything with it... if I try to login to dockerhub I get this issue

Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

No matter what I do, if I try to pull other image, or even just hello world...

my problem is that... I hope someone could help me
