Unable to download data from rubygems
<p>I don't know what this error means when trying to run <code>gem update --system</code>;</p>

<pre><code>{9:29}[2.2.3]~ ➭ gem update --system
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)
</code></pre>

<p>I also get a similar error when trying;</p>

<pre><code>{9:30}[2.2.3]~ ➭ gem install tunnelss
ERROR:  Could not find a valid gem 'tunnelss' (&gt;= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)
</code></pre>

<p>FYI - I can visit <code>https://api.rubygems.org/specs.4.8.gz</code> in the browser and it will start downloading so that's not the problem.</p>

<p>Don't really know what to try. Can anyone advise?</p>
