TLS errors and clients sometimes rejected

[Rodrigo Abrantes Antunes]

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 at SECLEVEL=0"
tls_min_version = "1.0"
tls_max_version = "1.2"

Any ideas what might be going wrong?
