Collabora CODE requires RSA certificate?


I have been trying to get collabora up and running an ran into problems.

SSL_do_handshake() failed (SSL: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher) while SSL handshaking

The fix turned out to be: Switch the letsencrypt certs from “key-type = ecdsa” to “key-type = rsa”.

Is Collabora CODE incompatible with ecdsa certificates or did I misconfigure something?
If there actually is an incompatibility: Is there a roadmap when support for ecdsa certs can reasonably be expected?
