In /etc/loolwsd/loolwsd.xml it is currently possible to configure the OpenSSL ciphers via <cipher_list></cipher_list>. With the recent deprecation of the TLS 1.0 and 1.1 protocol versions the possibility to disable both protocols is currently missing (either not implemented or maybe just not documented?). Please add the possibility in the loolwsd.xml to disable specific TLS protocols similar to e.g. Apache: https://httpd.apache.org/docs/2.4/mod/mod_ssl.html#sslprotocol
