That peer status billboard shows that this ntpd has not been able to
poll the remote time servers.

noserve blocks all NTP time service packets both incoming and
outgoing. This means that the default posture of this ntpd is to be
_neither_ a client nor a server.

notrust means to ignore all NTP packets unless they are

The broadcast delay line does nothing in your case.
Please comment out your restrict lines and restart ntpd. If that does
not work something is blocking 123/UDP.
