我在使用Rails中的postmark-mailer gem的deliver-later方法的邮件触发时得到了这个错误。

这是我的Ruby和OpenSSL环境：

Ruby:           2.6.4p104 (2019-08-28 revision 67798) [x86_64-linux]
RubyGems:       3.0.3
Bundler:        2.2.25
Compiled with:  OpenSSL 1.1.1f  31 Mar 2020
Loaded version: OpenSSL 1.1.1f  31 Mar 2020
SSL_CERT_FILE:  /usr/lib/ssl/cert.pem
SSL_CERT_DIR:   /usr/lib/ssl/certs

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

Bundler connection to rubygems.org:       success ✅
RubyGems connection to rubygems.org:      success ✅
Ruby net/http connection to rubygems.org: success ✅

Hooray! This Ruby can connect to rubygems.org. You are all set to use Bundler and RubyGems.
