gem update fails with a certificate verification error
Whenever I execute
gem update or
gem update --system it returns this error:
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)
This is on Ruby 2.1.5 with Gem 2.4.2 on Windows 7 x64.
I'm using the x64 version from here: http://rubyinstaller.org/downloads/
This is 100% reproducible, in a normal and in an elevated command prompt.
Not sure if this is a security problem. I'm fairly sure this problem did not exist a couple of days ago, using the exact same client. This indicates there's a problem on the remote server, and not really on my end.
