It would be helpful to know what version of Git, libcurl, and operating system you're using. This type of error is often caused by proxies, including non-default antivirus or firewall programs (very especially on Windows), TLS middleboxes, and monitoring software. If you have such software, it should be completely uninstalled and you should reboot, and usually that will fix the problem. (Simply disabling it often does not fix things.)

I should point out that while I'm aware that this does occur for many people, I have never, ever seen it when using GitHub, nor do I believe it is actually sent by GitHub servers. Thus, my experience leads me to believe the problem lies elsewhere. It is theoretically possible that libcurl or one of its dependencies has a bug in your version, but without more details, it's hard to tell.

As Junio suggested, you could try forcing HTTP/1.1 and see if that fixes the problem for you as well.
