We are trying to get our comodo certificate installed and running for our mobility installation. Here is what I have (and by no means am I certificate/mobility/Linux expert)

I have 3 .crt files... one for the server, one for comodo, and one for an external ca root. Reading the other threads on SSL certs, it looks like you just combine the 3 of them and place them in /var/lib/datasync/device/ and then rename it to mobility.pem. When I do that and restart the datasync services it seems to just shut down. It shows the engines are running, but from the outside I can no longer telnet on port 443. Like I said, total nube, but would like to get this working... any help would be much appreciated... thanks!
