this isn't the first time, but after a while my ntp stops working :(
i dont know what to do...

any suggestions?

It's /etc/ntp.conf if you're using the ntpd that comes with the base
system in FreeBSD.  Unless you're running you own PPS clock or engaged
in developing NTP, there's much point in installing the ports version.

Even so, it seems you have a problem connecting to a remote NTP server.
Can you do the following:

First, choose one of the IPs returned from one of those pool.ntp.org
addresses:

% host 0.us.pool.ntp.org
0.us.pool.ntp.org has address 216.45.57.38
0.us.pool.ntp.org has address 64.22.86.210
0.us.pool.ntp.org has address 69.36.241.112
0.us.pool.ntp.org has address 69.56.251.238
0.us.pool.ntp.org has address 169.229.70.201

Then test that you can get NTP packets to and from between that machine
and your own by using ntpq(8):

% ntpq -p 216.45.57.38
    remote           refid      st t when poll reach   delay   offset  jitter

If you don't get output like this showing a list of reference servers
from any of the available addresses, then I'd suspect something like
over restrictive firewall rules blocking the traffic.  If you do get
a response then the problem is localised on your machine.  In which
case, try stripping out and NTP related ports you've installed,
configure the base system ntpd(8) and see if that works better for you.

        Cheers,

        Matthew
