TrueNAS System Certificates - elliptic curve cryptography

[QonoS]

Hi folks,

I have been running TrueNAS for while and server certificates expired. So I tried to generate new ones.
Since EC requires less computation and is more secure of course i go for that but....

Nothing works. I tried lots of combinations when generatiing and Firefox & Chrome are acting similar. It is always : err_ssl_version_or_cipher_mismatch

Only RSA is working. Why ? Seems other people have had the same problem already some years ago.
Anybody got it working ? How ?

PS: Please no discussion RSA vs EC. EC is offered by UI so it HAS TO WORK somehow.

Did you use the UI to create the cert or did you generate your own and imported? Just wondering.

I used the UI to generate CA & certificates.
