Hi All I have Openconnect server up and running and clients can connect fine. But the connection protocol is always TLSv1.2. It does not seem to use DTLS, no matter which client I use (Cisco Anyconnect on MacOS, iOS and Android and OpenConnect for Android). OS: Ubuntu 17.04 ocserv version: ocserv/zesty,now 0.11.6-1 amd64 [installed] certificate: obtained via certbot OpenSSL 1.0.2g relevant ocserv.conf settings: server-cert = /etc/letsencrypt/live/myname.me/fullchain.pem server-key = /etc/letsencrypt/live/myname.me/privkey.pem try-mtu-discovery = true tls-priorities = ?NORMAL:%SERVER_PRECEDENCE:%COMPAT:-VERS-SSL3.0" #match-tls-dtls-ciphers = true cisco-client-compat = true #dtls-psk = false dtls-legacy = true Also, there is no ocserv logfile in /var/log. Where is the location for the log file? Appreciate any advice or pointers where to troubleshoot. Thanks
