I am running ntpd on a CentOS 6.9 server and my configuration for ntpd had been working without issue previously. Typically, it takes a little time but it will sync up with an higher stratum server after a period of time.
However, after I performed a kernel update last night, the server refuses to connect to any of them. It still shows everything besides the local peer as stratum 16.

I am using the following servers in the config.
server 0.north-america.pool.ntp.org
server 1.north-america.pool.ntp.org
server 2.north-america.pool.ntp.org
server 3.north-america.pool.ntp.org
ntpd is configured with these parameters.
restrict default noquery notrust nomodify notrap
I have tried stopping ntpd, doing a ntpdate -s/-u then starting ntpd again. It appears to adjust the clock at the time I run ntpdate, but refuses to sync up via the service. Everything just remains stratum 16 indefinitely.
