An error appears in Ruby's OpenSSL gem when trying to connect to a Google Service.

certificate verify failed (unable to get certificate CRL) (OpenSSL::SSL::SSLError)

This issue is introduced by a behavioral change in the underlying OpenSSL library, and a patch for the OpenSSL gem (v3.3.1) is available. The detail is documented here: https://github.com/ruby/openssl/issues/949


To apply the fix, you should explicitly declare the openssl gem in your Gemfile. Otherwise, it might still be resolved to the older version.

gem "openssl"
