 Here's your Ruby and OpenSSL environment:

 Ruby:           2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux-gnu]
 RubyGems:       3.0.3
 Bundler:        1.17.2
 Compiled with:  OpenSSL 1.1.1  11 Sep 2018
 Loaded version: OpenSSL 1.1.1c  28 May 2019
 SSL_CERT_FILE:  /usr/local/ssl/cert.pem
 SSL_CERT_DIR:   /usr/local/ssl/certs

 With that out of the way, let's see if you can connect to rubygems.org...

 Bundler connection to rubygems.org:       failed  ❌  (Net::OpenTimeout)
 RubyGems connection to rubygems.org:      success ✅
 Ruby net/http connection to rubygems.org: success ✅

 Although your Ruby installation and RubyGems can both connect to rubygems.org, Bundler is having trouble. The most likely way to fix this is to upgrade Bundler by running `gem install bundler`. Run this script again after doing that to make sure everything is all set. If you're still having trouble, check out the troubleshooting guide at http://ruby.to/ssl-check-failed 📦
 (eval):136: warning: constant OpenSSL::SSL::SSLContext::METHODS is deprecated
