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

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"

A change in the underlying OpenSSL library can cause Ruby’s OpenSSL gem to fail certificate verification when connecting to Google services. The issue is fixed in a patched openssl gem (version 3.3.1) and documented upstream. To ensure your application uses the corrected release instead of an older one, explicitly declare the openssl gem in your project’s Gemfile so dependency resolution picks the patched version.
