Right. It might just be my Hiberno English, as my usage of the word "issue" wasn't meant to indicate a flaw. In this case, I intended it to mean the source of the behaviour I was seeing.
Anyway, I'll look into upgrading OpenSSL. many thanks!

You need probably OpenSSL 1.1.1 or newer. You can check as well ciphers -v | grep TLSv1.3 to see the proper Cipher Suite Names (IANA) usable for e.g. TLSv1.3 -gn On 23.03.20 18:08, Brian Fenton wrote: Hi Gustaf Ah this is an OpenSSL issue, not Naviserver.

Dear Brian, What version of OpenSSL are you using on what OS? Are these ciphers available in this OpenSSL implementation? openssl list -cipher-algorithms It might be possible, that the same version of OpenSSL has on different platforms/distributions different ciphers included.
