        I have opened https://redmine.pfsense.org/issues/9106 to track this, but we can't do anything until we can either reproduce it locally, or get the debug log messages stating exactly what part of the test failed.

        After gathering the above info, I do have a hunch as it what might help. Install the system patches package and then try the following patch:

        diff --git a/src/etc/inc/vpn.inc b/src/etc/inc/vpn.inc
        index d12eb986c2..c055a04d66 100644
        --- a/src/etc/inc/vpn.inc
        +++ b/src/etc/inc/vpn.inc
        @@ -1556,6 +1556,7 @@ EOD;
         	}
         
         	/* manage process */
        +	mwexec("/etc/rc.d/ldconfig start", false);
         	if ($restart === true) {
         		mwexec("/usr/local/sbin/ipsec restart", false);
         	} else {
        

        If that doesn't help, revert the patch.

          Thanks for opening the issue for tracking.
          Retried the update with the same problem. I changed the log level to highest as requested and started IPsec but it unfortunately did not report more information:

          Nov 11 23:56:33 	ipsec_starter 	19939 	ipsec starter stopped

          I also tried the patch but it did not change anything.
          Reverted back to 2.4.3 for now.
          Let's see if dtrandov as better results.

            Did required changes, but no additional info in log files and IPsec refused to start.
            Just for test i ran again pkg check -s strongswan, and some files are missing:
            pkg check -s strongswan

            I'm sure when issue arise, I did reinstall strongswan and no errors appears.

              The man pages being missing is expected, as we normally will strip out the man pages and other docs from the host itself to save space.

              I was hoping that little patch would help, but at least we know it isn't the library path.

              If you can get a host back into the failed state, try going to an ssh or console shell prompt and then run this command:

              ipsec stop
              ipsec start --debug-all
              

              And then check the console output and IPsec log

                  OK, that is a different condition. It doesn't like a . in the RADIUS server name. I didn't have any set that way, but now that I set one up I see the same error. Curious that the error is shown on the console but not in the logs. But now I do see the same integrity test error!

                  So we're getting closer! Let me find a fix for this, most likely it will involve removing the dots or swapping them for some other character.

                    Great.

                    well, I've just defined new radius server entry (without dots in name) in System/User Manager/Authentication Servers and IPSec is up now..... definitely dots in name are problematic.

                      Thankfully that is a very simple fix (assuming you don't fudge the regex like I did on my first commit), so if you want to keep a RADIUS server entry with . in the name, you can if you apply the following patch:

                      diff --git a/src/etc/inc/vpn.inc b/src/etc/inc/vpn.inc
                      index 2458a224f5..e3ccb4f3c4 100644

                          Thanks jimp!
                          I'll try this also tonight and post results.
                          Quick question: (I'm no expert with diff.) Shouldn't the path in the above patches be /etc/inc/vpn.inc? There is no /src folder on our system.
                          Also, will this be corrected is a future release or will we need to keep the patch as long as we have names with dot?

                            It will be corrected in 2.4.4-p1 and 2.4.5.

                            As for the path, the system patches package defaults to a path strip level of 2, so it will do the right thing here.

                            The source in github has a src/ directory prefix, which is why it shows in patches made from git commits like the above.

                              Understood for the default strip level of the system patches package.
                              This worked also for us and we now have a working 2.4.4 system.
                              Thanks jimp!
