Hi, sometimes clients are rejected with the errors below, and sometimes the same clients are accepted. I thought that this could be because of old clients and then defined this but the errors continued: cipher_list = "DEFAULT@SECLEVEL=0" tls_min_version = "1.0" tls_max_version = "1.2" Any ideas what might be going wrong?
