Hello I generate a CA (self signed), and then generate a certificate from that CA, which should be used by a HTTP/2 client and server during testing. This code was working as recently as 12 months ago, but it seems like something has stopped it from verifying correctly. Here is how the CA is generated, along with a certificate store which is used for verification: https://github.com/socketry/async-rspec/blob/4e4c2e59fdb93daab0aa11917f02a05d0fd746e3/lib/async/rspec/ssl.rb#L47-L79 Later, this CA is used to generate a certificate: https://github.com/socketry/async-rspec/blob/4e4c2e59fdb93daab0aa11917f02a05d0fd746e3/lib/async/rspec/ssl.rb#L85-L110 Finally, we want to check that this is a valid configuration: https://github.com/socketry/async-rspec/blob/4e4c2e59fdb93daab0aa11917f02a05d0fd746e3/spec/async/rspec/ssl_spec.rb#L35-L37 Like I said, this was passing, as recently as April. However, it's now failing with error code 18: "self signed certificate". I've tried a number of things but cannot figure out what's changed and what I need to do to make this work again (except disable verification completely which is not what I want). Any ideas what I need to do to make this work again? Thanks Samuel
