SSL Certificate Update
If you’ve seen the following SSL error when trying to pull updates from RubyGems:
OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed
This error happens when your computer is missing a file that it needs to verify that the server behind RubyGems.org is the correct one.
Follow the steps outlined in the RubyGems and Bundler OpenSSL/TLS guide to troubleshoot the problem.
If you’re still encountering issues, you can open an issue on GitHub.
