      Hello!

      I installed pfSense 2.3.2 and wanted to give pfBlockerNG a try. I activated the EasyList for DNSBL, but there is an error when unbound is supposed to be reloaded during the update/refresh.

       UPDATE PROCESS START [ 09/29/16 17:54:50 ]

      At the same time these messages appear in the DNS Resolver log (newest line at the top). Never mind the different time stamps to above, I tried it multiple times.

        Did you enable DNSSEC in the Resolver? If you're using the Resolver in "Forwarder mode", ensure that the DNS Servers that your using support DNSSEC.

          Thanks for getting back so quickly. DNSSEC was enabled, forwarding was not. I disabled DNSSEC, restarted unbound and tried again, but the messages remain the same on both fronts.

            Enable "Suppression" in the pfBlockerNG General Tab, then run a "Force Reload - All" and see if that fixes it for you…

            Does this command execute ok?

            unbound-control -c /var/unbound/unbound.conf status

              Enabled suppression and tried again, still the same.

              And no, the command does not execute OK:

                Something is wrong with the Resolver installation… Leave DNSBL disabled for now, and post in the DHCP/DNS section to see how to fix that issue with the base software...

                Make sure to post what version of pfSense you are using. Or maybe try a fresh install and copy back you current config?

                Once you have the Resolver functional, then re-enable DNSBL...

                  All right, thanks for your help.

                  One more thing: When I ran the unbound-control command just then I was NOT logged in as admin/root, but as another user who I thought had the same rights, which does not seem to be true. Running as root gives me

                  unbound-control -c /var/unbound/unbound.conf status
error: SSL handshake failed

                    I don't know how, but a reboot seems to have fixed it. unbound doesn't throw any errors, and DNSBL work as they should.

                      I had the same problem, restart didn't work for me.

                      What did help is that I disabled EasyPrivacy in DNSBL EasyList.

                      Not sure why this happened exactly, but maybe it will help people out who find this topic.

                        I had this same Error: Reloading Unbound… Failed to Reload... Restoring previous database.... Not completed.

                        Disabling EasyPrivacy in DNSBL EasyList also worked for me.

                        Using PFSense 2.4.2 p1 latest release

                          I had the same issues and found another solution:

                          Sometimes the certificates generated by ubound are not valid (by time/date/etc.).

                          Solution: delete all certificates from ubound in the folder /var/ubound/ - than restart pfsense/ubound.

                                        @noplan Many thanks. Removing those files (dated 1969) and restarting the Unbound service worked for me
