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

A simple restart fixed it for me  I m not sure what was the problem since I work with so much software but I have a feeling it was the VPN software or maybe the fact I put my laptop in sleep a lot and some file was corrupted  I really don t know but the restart fixed it

Same problem here  it turned out to be my incorrectly configured proxy settings  here s how to check and remove them   First open your git config file   vi    gitconfig   and find out whether the  http  or  https  sections are set   I used to set proxies for git due to slow access to Github in China  however  lately I changed my local proxy ports but I forgot my git settings   If you have incorrect proxy settings and decide to remove it  simply execute   git config --global --unset http proxy git config --global --unset https proxy   Things will work just fine

I have a similar issue and I just found that in my case it may be the antivirus that creates an issue   At some moment I ve got the same error while trying to pull some data from github com   I knew that Kaspersky is intercepting the SSL connections to check for malicious content from the sites and I decided to disable it  but I found that KAV is hung and not really responding  so I just closed Kaspersky and tried to connect to github com again and alas  I was able to connect successfully to GitHub   So in you case it may be a similar issue

I had this similar error when using wget      and after much unfruitful searching in the Internet  I discovered that it was happening when hostnames were being resolved to IPv6 addresses  I discovered this by comparing the outputs of wget     in two machines  one was resolving to IPv4 and it worked there  the other was resolving to IPv6 and it failed there   So the solution in my case was to run networksetup -setv6off Wi-Fi on macOS High Sierra 10 13 6   I discovered this command in this page    Hope this helps you

The problem for me seems to have been how the user has been setup on my local machine to  Using the command  git push -u origin master  was causing the error  Removing the switch -u  to have git push origin mastersolved it for me  It can be scary to imagine how user setup can result in an error related to LibreSSL

Hi everyone I found the solution regarding this github issue and it works for me  no longer able to use private ssh key  Try following theses steps   1 - Use HTTPS if possible  That will avoid SSH keys entirely  2 - Manually add the SSH key to the running SSH agent  See manually generate ssh key 3 - If the two others doesn t work  delete all your ssh keys and generate some new one thats what I did after weeks of issues   Hope it will help you
