Docker push - net/http: TLS handshake timeout

I got the same issue, this issue is may be from your internet connection, I solved it by decrementing the concurrency uploads (downloads for get) to 1 in dockerd. By using these args:

--max-concurrent-downloads  (default: 3)    Set the max concurrent downloads for each pull

--max-concurrent-uploads    (default: 5)    Set the max concurrent uploads for each push

uploading 5 images in same time may result a timeout if you have a low bandwidth.

Just adding a separate answer for those who may be dealing with it on a managed build environment like Azure Devops based on https://github.com/actions/virtual-environments/issues/2152#issuecomment-736325518

Change the setting as follows

sudo sed -i 's/ }/, \"max-concurrent-uploads\": 1 }/' /etc/docker/daemon.json
sudo systemctl restart docker
