Since you're using LibreSSL, try re-installing curl with OpenSSL instead of Secure Transport.

Latest Brew

All options have been removed from the curl formula, so now you need to install via:

brew install curl-openssl

Older Brew

Install curl with --with-openssl:

brew reinstall curl --with-openssl

Note: If above won't work, check brew options curl to display install options specific to formula.

Here are few other suggestions:

• Make sure you're not using http_proxy/https_proxy.
• Use -v to curl for more verbose output.
• Try using BSD curl at /usr/bin/curl, run which -a curl to list them all.
• Make sure you haven't accidentally blocked curl in your firewall (such as Little Snitch).
• Alternatively use wget.

2)Just ran these two statements before pushing the code. All I did was to cancel the proxy.

$ git config --global --unset http.proxy
$ git config --global --unset https.proxy

3) Faced the issue again after couple of weeks. I have updated homebrew and it got fixed
