There was a regression in 0.23.23 and later where an empty value passed in ConfigBuilder::with_single_cert_with_ocsp() resulted in sending an empty OCSP value (instead of not sending anything). Thanks to @vuongDang for reporting and fixing.

What's Changed

• Backport empty OCSP fix for 0.23.35 by @djc in https://github.com/rustls/rustls/pull/2734
