Thanks for the quick merge. I ended up looking here from an issue in RG, what do you think about adding something like the file mentioned in:

ruby/rubygems#8390 (comment)
The file is:
https://github.com/MSP-Greg/ruby-ssl-check/blob/00-ssl-code/ssl_connect.rb

I work with the three main OS's, and I don't recall ever having ssl issues. I'm using Ruby master on all three also. When people have the http test here failing, I have no idea what the issue might be.

Maybe the cert store, we could some minimal tests of it? Not sure...

@MSP-Greg per my understanding net/http is using openssl also. But if there's any test in your script missing in current check.rb, feel free to update check.rb to add it.

Same here. I was just hoping (possibly incorrectly) that dropping to the socket level might provide better error messages.

I work with Puma, and net/http understandably won't allow one to create invalid requests. Hence, a lot of test code runs at the socket level...
