Re: OpenSSL-1.1.1a - No TLSv1.3 with unbound

Hi,

This is a bit weird.

Does the version of unbound support TLS 1.3? We had to update Apache to support TLS 1.3 and we had to just rebuild haproxy to support it, too. Since you are running a build of unbound that was built against OpenSSL 1.1.1 I would say the latter isn’t likely.
