      "DNS Resolver is stopped or Disabled" when we chk the tatus of DNS Resolver.
      In the DNS Resolver page, the Enable DNS Resolver tick mark is ON
      May be NTP server setting is not resolving ??????
      DNS Resolution behavior is set as Default.(First use local and fall back to remote)

      DNS forwarder is ON and working.

        Then the NTP client can resolve.

            14 Jun 19:14:57 ntpdate[69805]: no server suitable for synchronization found

            This response means any issue with DNS ?

              Noop.
              A (the pfSense) NTP client syncs with an NTP server, typically an IP (and in that case : no DNS needed ;) ), a host name or even a pool.
              It tells you it wasn't able to do so.

              Example :
              I'm in France, so I used a local NTP server pool :

              6e2fe29c-1c5e-4541-8535-11ca27baa4a0-image.png

              Because you should never 'type in stuff without checking, I've checked this "2.fr.pool.ntp.org" :

              [24.03-RELEASE][root@pfSense.bhf.tld]/root: dig @127.0.0.1 2.fr.pool.ntp.org +short
              195.154.226.102
              149.91.80.92
              91.224.149.41
              82.64.81.218
              

              This tells me 3 things :
              The pool is a pool, there are several IPs.
              The 'host name' resolves to IPs.
              And, bonus : my DNS works.

              My 'NTP' is happy of course :

              7952f4c1-cfca-44de-8da2-a7297897a01d-image.png

              Hummm : the status told me my check was wrong ....
              Ok, again :

              [24.03-RELEASE][root@pfSense.bhf.tld]/root: dig @127.0.0.1 2.fr.pool.ntp.org AAAA +short
              2001:41d0:801:2000::acb
              2001:41d0:304:200::6803
              2603:1020:802:3::a8
              2001:861:4080:81b1::3
              

              Also fine.

                  @Cleetus-Antony well your never going to sync if you can not resolve anything in the pool name your using.

                  If you try and resolve that fqdn, what do you get back?

                  Also you have 2 notifications I see up there the red bell with 2 next too it - those are normally things you should pay attention too, and quite often point out stuff that had an error, etc..

                      @Cleetus-Antony ok well its resolving... So that is good.. Odd that ntp doesn't show that, I would think it would show the IPs it resolved and then if couldn't talk to them the reach would just be at zero, etc..

                      But yours is showing nothing, like it couldn't resolve what IPs are in the pool? Is that maybe a O vs a 0 (zero)?

                      You could try putting in say one of those IPs directly vs as a pool and see if it shows that IP.. And can it talk to it.. I would then sniff on your wan to validate its sending ntp, and maybe you just don't get an answer?

                        Do you have a PC with a windows OS ? or any OS actually, as every device has a ntp client these days.
                        Get any of the IP's, and give it to your ntp windows client :

                        55f88f52-5a90-4d65-8d9a-4fab690c19dc-image.png

                        and test it.

                        Still doesn't work ?
                        Start checking your upstream 'WAN' (ISP ?) connection. Some one might be filtering upstream.
                        You don't have any pfSense floating firewall rules, right ?

                          I have no additional rules set. All default ones.
                          Before this ntp, I used pfsense default ntp settings. Stil the issue was same.

                            I put one of the ip into ntp. its not reaching.

                            But from pfsense, its pinging.

                              The firewall can notify administrators of important events and errors by displaying an alert in the menu bar, indicated by the bell icon. Out of cuirosity what are your notifications?

                                @Cleetus-Antony pinging is different than ntp.. While ping is good that you can actually get there.. Doesn't mean its answering ntp, or that it even sees your ntp query..

                                First thing is to actually validate your ntp query is leaving your wan, and has been natted to your IP.. If you see the query go out - and get no answer.. Not something pfsense can have any control over.. You would then need to look up stream if something is blocking, etc...

                                  Notifications was not related NTP.
                                  It was abt some user settings.

                                    I checked with a windows client pc connected after the pfsense and configured the ntp 1.in.pool.ntp.org and synced the time. it does well. but the same ntp server is not reaching in pfsense... strange huh ?

                                    My pfsense is behind the FTTH modem/router in which 1.in.pool.ntp.org is configured and it does the job. So we can conclude that this ntp is not being blocked in upstream right ???

                                      if your client can talk to it, yeah - but still doesn't validate pfsense is actually sending or natting the traffic.. Or that it likes the answer? A simple sniff would allow you to validate that it talks and gets an answer and what that answer actually was, etc.

                                      It takes all of a few seconds to do a sniff.. Longest part would be waiting for the timer of when ntp would resend, which is like 64 seconds.

                                      Also ntp 1.in.pool.ntp.org is not what you were showing you were using in pfsense.. You were using 0. Or the 1 specific IP, etc.

                                          @Cleetus-Antony dude limit your sniff to port 123.. On pfsense WAN... Your wanting to see what is happening when pfsense ntp is asking..

                                          Make sure none of your clients are asking outside ntp during your testing.

                                          If you don't see anything - and the counter has cycled through a couple of times on pfsense - then that would explain why its not working - for whatever reason pfsense is not sending ntp out your wan..

                                          Are you routing traffic through a vpn or something?

                                            I set the filter tcp.port ==123 and saw nothing matching traffic in wireshark. As u said pfsense is not sending any ntp request out I guess.
                                            I set an outbout WAN rule also to NAT anything out from the firewall itself... still no effect.
                                            I did even reset the state of firewall also.
                                            As u asked, I am not routing traffic through a vpn.
                                            I am using version 2.7.2 the latest one. Is there any bug ?
