Hi, facing [ no shared cipher ] error with EC private keys. This happens when the private key is generated with [ openssl ecparam -name brainpoolP512t1 -genkey ] with OpenSSL 1.1.0hh on the same machine Dovecot is running on.
Tried some variations of [ ssl_cipher_list ] but to no avail - the [ no shared cipher ] error persists. Once the key is generated with [ openssl genpkey -algorithm RSA ] however the error is gone. Thus wondering whether (1) I am missing something or (2) this a bug or (3) there is no support for EC keys?
