      I'm able to ping the NTP server and pull up it's GUI.

      This seem more like some general connectivity issue and not specifically NTP related.

      How is the NTP server connected? How are the clients you're testing from connected? Do you see blocked traffic?

      Everything is connected via ethernet. No blocked traffic that I can tell.

        Sorry I mean is everything on the same subnet? Same interface in pfSense? Or is pfSense routing that traffic maybe?

          Ah, the NPT server is on a management VLAN where I keep all my switches, access points, IPMI addresses, etc. I'm able to access it from my other VLANs though.

            Oh wait I misread that as 'unable' to access. Ignore me! 🤦

                  I think it's just a label or the way I configured my ntpsec, either way this shows that pfsense is able to communicate with your ntp server on port 123

                  the only way for me to have a Unreach/Pending state is when i select an isolated interface that is unable to reach my ntp server.
                  did you try to change the interface where it's listening? like localhost only ?

                      @ARAMP1 sounds like the same issue I have with the plus version 23.09:

                      https://forum.netgate.com/post/1136805

                      NTP works again going back to previous version (23.05.01)

                      I just read through your thread again. I noticed that you were able to point specific machines to the IP address of your NTP server and bypass pfSense. I really want/need a windows machine that I run Blue Iris on and all of my security cameras to be synced, so I did that for that windows machine and it works fine.

                        They have a Redmine open for NTP authentication issues I think the patch that Marcos and Matthew merged might also fix this. The GitHub was merged a couple days ago but has not been looked at but it looked to incorporate many fixes not just authentication issues.

                          Well, it's taken me quite a few hours to get to this post.
                          I went to check my time precision this morning and noticed that the graphs were all way out.
                          Checking when it started, it was right after I upgraded to 2.7.2.
                          Looking at my local Stratum 1 NTP server, it's pending/unreachable and the firewall has fallen back to time.apple.com

                          With the basics checked, then ACL's adjusted and even firewall rules put in, the ntpupdate -4 command showed that everything is working as it should. (And likely was before I did anything other than upgrade...)
                          pfsense just refuses to accept any NTP traffic from the LAN side of the house.
                          Right when I was starting to think it couldn't be much else than a system issue, I found this thread.
                          As well as confirming that some of us take time seriously, it was nice to know that we've got the same issue.

                          Looks like a roll back is in order, or just wait for the patch

                            Even though there are issues with this (and also the ARP table showing permanent entries), I've decided to keep it at 2.7.2. I still show a stratum 1 using the nist.gov clocks. The only issue would be if the internet goes down. If it becomes an issue with individual machines, I'll direct them to my local NTP server then.

                              just to pile on one more, I have the same issue on 23.09.1 on two 6100s with a local TM2000 on the same lan. I tried all of the things mentioned in these threads with no changes. It looks like it broke on 23.09 for me as well (after reviewing the RRD after I noticed the issue).

                                  it is not fixed, also not able to get it to work in 24.03

                                    Seems the newer versions of software function by way of a different pair of spectacles. I have a number of issues versus older reliable versions. I can tell you I personally like the old software better, it functions and feels far more resilient. I wonder why, I really do. I shouldn’t feel less trust with the new software. Again I hate to admit it’s starting to feel like that. Leading to, I shouldn’t feel afraid to upgrade. I use to get excited about even upgrade, now I question what is going to be broken if I upgrade. I am fearful of updates. Weird right? Is it big tech influence? Who knows, maybe I am just paranoid and don’t want to risk it now that I have it working way I want. Sorry it isn’t working

                                      Seems the newer versions of software function by way of a different pair of spectacles. I have a number of issues versus older reliable versions. I can tell you I personally like the old software better, it functions and feels far more resilient. I wonder why, I really do. I shouldn’t feel less trust with the new software. Again I hate to admit it’s starting to feel like that. Leading to, I shouldn’t feel afraid to upgrade. I use to get excited about even upgrade, now I question what is going to be broken if I upgrade. I am fearful of updates. Weird right? Is it big tech influence? Who knows, maybe I am just paranoid and don’t want to risk it now that I have it working way I want. Sorry it isn’t working

                                      Fully agreed!
                                      That's the reason why I did not upgraded all my boxes yet.
                                      Firewall software with a bad gut feeling is a "no go" (for me).
                                      So I am started to thinking about changing the system with the next (hardware) cycle....

                                            To be honest, not sure yet. Just started thinking about it....

                                            I ordered some parts for setting up a tiny LAN server to free pfSense from
                                            some tasks or services. Its nearly 200ish € but its worth in my eyes.

                                            RaspBerry PI 4 B (8GB)
                                            GPS hat (u.blox M8)
                                            Micro SD card 64 GB
                                            mSATA board x857
                                            active magnetic GSP antenna (5 meter cable)
                                            USB C - PSU

                                            Later it should run the following services;

                                            • PI hole or CrowdSec
                                            • syslog-ng server
                                            • NTP (Internet, RTC, GPS)
                                            • RadiusServer (FreeRadius)
                                            • LDAP server (OpenLDAP)

                                            Eventually later a DCF77 kit over USB but this is actually only brainstorming.
                                            So for the entire network it will be then a Stratum1 NTP server with RTC,
                                            GPS and over the internet with 4 pools and 4 servers.
