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

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.

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:

54.188.157.32 homebrew.bintray.com

Solution 2:[2]

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

Solution 3:[3]

It looks like there is currently a misconfiguration of the server or it is the wrong server to use. The server is not able to do any TLS handshake on port 443, no matter which client is used. From SSLLabs:

If you do not have permissions to modify your hosts file, you can also try this workaround:

~> HOMEBREW_BOTTLE_DOMAIN=https://dl.bintray.com/homebrew brew upgrade

to run the brew upgrade command while setting the HOMEBREW_BOTTLE_DOMAIN environment variable temporarily. It has solved my problem when upgrading my Brew packages.
