I don't have much info to go on here, looking for ideas as I've run out. I did a server certificate update on our tomcat box (FreeBSD 9.2). After reboot, any connections to it fail immediately (page not found in the browser). However, on the server side everything looks fine. Tomcat's listening on 443 on IPv4 and IPv6. No errors in the system logs. No errors in the tomcat (catalina) logs. The app deploys normally as far as I can tell. No firewall in between. No other configuration changes made, just a "simple" certificate replacement.
