I tried to do use the ssltest from qualys.com:
https://www.ssllabs.com/ssltest/

Every time i run it, my nginx server (ssl terminator) crashes and i have to restart it.

I get the following error in my nginx logs:

*734 SSL_do_handshake() failed (SSL: error:140A1175:SSL routines:SSL_BYTES_TO_CIPHER_LIST:inappropriate fallback) while SSL handshaking, client: ......, server: .......

I've got the following configuration:

server{
listen .........:80;

}
