[Users] unable to use spice-html5 in chrome due to certificate error

Hello, I think I have configured all ok. Fedora 19 with stable oVirt 3.3.1 Version 31.0.1650.63 I get a black window when using spice html5 in console options in /var/log/messages of engine I get Dec 7 18:51:16 tekkaman ovirt-websocket-proxy.py[22356]: 5: handler exception: [Errno 336265225] _ssl.c:351: error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib So I think the problem has to be the configuration part of Import CA of the engine in your browser can anyone gives instructions for dummies to do this, please? Then I'll put into the wiki when I'm able to use it... ;-) I see that in engine I have under /etc/pki/ovirt-engine lrwxrwxrwx. 1 root root 6 Feb 10 2013 apache-ca.pem -> ca.pem -rw-r--r--. 1 root root 563 Feb 10 2013 cacert.conf -rw-r--r--. 1 root root 505 Feb 10 2013 cacert.template -rw-r--r--. 1 root root 384 Nov 14 12:44 cacert.template.in -rw-r-----. 1 ovirt ovirt 4810 Feb 10 2013 ca.pem -rw-r--r--. 1 root root 557 Feb 10 2013 cert.conf drwxr-xr-x. 2 ovirt ovirt 4096 Nov 14 12:44 certs -rw-r--r--. 1 root root 557 Feb 10 2013 cert.template -rw-r--r--. 1 root root 483 Nov 14 12:44 cert.template.in -rw-r--r--. 1 ovirt ovirt 292 Feb 10 2013 database.txt -rw-r--r--. 1 ovirt ovirt 20 Feb 10 2013 database.txt.attr -rw-r--r--. 1 root root 20 Feb 10 2013 database.txt.attr.old -rw-r--r--. 1 root root 225 Feb 10 2013 database.txt.old drwxr-xr-x. 2 root root 4096 Nov 14 12:44 keys -rw-r--r--. 1 root root 548 Nov 14 12:44 openssl.conf drwxr-x---. 2 ovirt ovirt 4096 Nov 14 12:44 private drwxr-xr-x. 2 ovirt ovirt 4096 Nov 14 12:44 requests -rw-r--r--. 1 ovirt ovirt 3 Feb 10 2013 serial.txt -rw-r--r--. 1 root root 3 Feb 10 2013 serial.txt.old I've tried to import ca.pem and I'm requested a password if I try to import under certificates tab, while it seems to import if under certification authorities tab, but I continue to get that error.... Thanks in advance, Gianluca
