SSL error with Rubygems (unable to connect)

Question

I've installed a fresh version of ruby 2.3.3 via RVM and I'm attempting to install rails (gem install rails) however, when I do I receive the following error:

ERROR: Could not find a valid gem 'rails' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=error: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)

I have followed the instructions on the SSL cert page on rubygem to no avail. Every cert I can find within rubygems seems to match the most recent version.

I have also run gem update --system and receive the following error:

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
        SSL_connect returned=1 errno=0 state=error: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)

Lastly, here is the output of `gem env`:

this repo helped me figure out what was wrong with the ssl-setup on my machine: github.com/mislav/ssl-tools or this: github.com/rvm/rvm/blob/master/help/osx-ssl-certs.md — Sascha Kaestle

You can try to do this, it can fix your problems.

gem update --system --source http://rubygems.org/

Now you're ready to use gem update and gem install rails
