getting curl: (35) error:1400410B:SSL routines:CONNECT_CR_SRVR_HELLO:wrong version number every time I run brew

Question

Title. I've been unable to run brew due to this error. I'm not currently running any proxies or any other things that would disrupt online connection. When I run it in verbose, it prints this.

Answer 1

If you are just using curl for a post request, check that you are not using https instead of http.

Answer 2

This is an issue with their CDN.

See here: https://github.com/Homebrew/brew/issues/10739

A workaround would be adding this to your hosts file:
