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

Hello Michael, hello Erik,

sorry for the long delay here. :-\

I noticed the AESCCM issue with Unbound, and will have a look
at it (never observed these ciphers in the wild - i.e. web and mail
traffic - but that does not mean anything here).

At the moment, I do not have an idea what is going wrong
here (currently using 127-stable).

P.S.: It's CloudFlare, not Cloudflair. :-)

P.P.S.: Thank you for the DoT server list. I will update the Wiki page.

Thanks, and best regards,
Peter Müller
