OpenSSL::SSL::SSLError: SSL_read: unexpected eof while reading with OpenSSL 3.x

[voxik]

Executing excon test suite with Ruby 3.1 and OpenSSL 3.0, I observe following errors:

  Excon basics (ssl) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[2022-02-23 03:58:50] ERROR OpenSSL::SSL::SSLError: SSL_read: unexpected eof while reading
	/usr/share/ruby/openssl/buffering.rb:80:in `sysread'

This reminds me issues I had with Puma. There is also more details in ruby/openssl ticket

@voxik Thanks for the heads up. I don't think I've otherwise seen this, but I may just forget. Just let me know if I can help.

OpenSSL 3.0 is not widely available yet. But it is default on Fedora 36+ and CentOS Stream 9
