      Have you tried to reboot as suggested above? Also, no idea why did you use this thread since you definitely do NOT have the same error.

      Anyway.

      
      mkdir /var/unbound/test/
      cp -ax /var/unbound/*.{key,pem} /var/unbound/test/
      
      

      and try again.

        Works only once: every time  /var/unbound/test/ is deleted and I have to create again before saving settings

          No idea what kind of legacy configuration crap have you imported on all of your boxes across some upgrades, sorry. You can try with 2.3.3 but I sincerely doubt it'd change anything. Other that that

          • wipe /var/unbound altogether
          • switch to DNS forwarder
          • make a config backup, wipe everything between <unbound>…</unbound> tags, restore the config (will force a reboot)
          • reconfigure the resolver from from scratch

            @Fabio72:

            Same here too.

            _The following input errors were detected:

            The generated config file cannot be parsed by unbound. Please correct the following errors:
                /var/unbound/test/unbound_server.key: No such file or directory
                [1484738643] unbound-checkconf[70766:0] fatal error: server-key-file: "/var/unbound/test/unbound_server.key" does not exist_

            I have to execute this everytime there are changes to be made:
            _  mkdir /var/unbound/test/
              cp -ax /var/unbound/*.{key,pem} /var/unbound/test/_

            I am also getting this error on DNS Resolver log: (a lot of them)
              notice: remote address is 192.168.2.245 port 53134
              notice: sendmsg failed: No buffer space available

              Not sure where this /test dir is coming from.. I look on my /var/unbound dir and I don't see any test dir..

              I can change my unbound conf without any issues.

              Are you running 2.3.3 or 2.4 of pfsense??

                  So from the code it looks like that sub dir is created but then removed after the test

                  
                  function test_unbound_config($unboundcfg, &$output) {
                  	global $g;
                  	$cfgsubdir = "/test";
                  	unbound_generate_config($unboundcfg, $cfgsubdir);
                  	unbound_remote_control_setup($cfgsubdir);
                  	do_as_unbound_user("unbound-anchor", $cfgsubdir);
                  	$cfgdir = "{$g['unbound_chroot_path']}{$cfgsubdir}";
                  	$rv = 0;
                  	exec("/usr/local/sbin/unbound-checkconf {$cfgdir}/unbound.conf 2>&1", $output, $rv);
                  	rmdir_recursive($cfgdir);
                  	return $rv;
                  }
                  
                  

                  rmdir_recursive($cfgdir);

                  So something is failing here?  Just not sure what..

                    I'm also having this problem. Setup pfSense from scratch on 2.3.3_p1.

                    The below does indeed work once off, so I need to run it every time I change the configuration.

                    mkdir /var/unbound/test/
                    cp -ax /var/unbound/*.{key,pem} /var/unbound/test/
                    

                    Is there a bug logged for it already?

                      For me the problem is gone away and I did nothing (neither reboot).
                      After updating to 2.3.3-p1 everything is still working.

                      But now is happening again on another site with a fresh new installation of a 2.3.3-p1  ???

                        Ok, now I have the problem again.
                        Sometimes happens and usually a reboot fixes it.

                          Just want to chime in here. Starting to see this on my pfsense running 2.3.3-RELEASE-p1 (amd64)
                          Configuration created from scratch so no "old crap" should be there. The workaround with mkdir and cp works.
                          Reboot doesn't solve this.

                            So to Recap:

                            • Reboots - DO NOT WORK

                            • mkdir Test and cp config - Works once per saved change

                            • move to forwarder, wipe unbound directory and return to resolver - ? ? ? ? ?

                              Anymore suggestions

                              This is the message I get when making any changes

                              The following input errors were detected:
                              The generated config file cannot be parsed by unbound. Please correct the following errors:

                              I am running:

                              The system is on the latest version.
                              

                              HELP!!!

                              Let me add to my previous, DNS is resolving all local addresses and appears to be working correctly.
                              But even if I attempt to make changes directly to the dhcp.conf, hostentries.conf or dhcpleases_entries.conf the changes to not persist after a process restart.

                              So this unbound config validator issue I more spread than I thought and more annoying than willing to deal with.

                                I'm facing this problem too, although not been able to clearly determine when and what triggers this.
                                Depending on DNS configuration (but what?), I get this same error message.
                                As far as I remember, occurred with all 2.3.x version (currently running 2.3.4)

                                I'm also facing problem with, if I'm not wrong, DNS stopping from time to time when DHCP registration is activated.

                                Weird  :(

                                    This is not a general problem that happens out of the box or with anything I have readily available. Something specific to your setups is causing this, but it's not clear yet what that is.

                                    There must be some missing detail to reliably replicate it. Please compare other system settings and setup details, like what platform/architecture is in use (e.g. NanoBSD or full), if you have /var and /tmp in RAM disks, and anything else about the setup that might be different or unusual, especially any packages you have installed.

                                      I remember few days ago after clean install of 2.3.4, and right after I restored 2.3.2 config, unbound was down and did not wanted to start up until I deleted the line added by pfblocker…```
                                      server:include: /var/unbound/pfb_dnsbl.conf

                                      
                                      Today I found unbound dead… and I blame wan lose connection that also triggered unbound death.

                                        I have also just faced this problem on my 2.3.5-RELEASE-p1 (i386) nanobsd (2g). Interesting is, that adding Host Overrides does not trigger the problem, although it changes and saves DNS Resolver configuration.

                                          Just ran into this on 2.3.4-RELEASE (amd64)

                                          Haven't had a chance to try any of the suggestions earlier in the thread, but this is a relatively new box that hasn't been around long enough to have legacy configs. Has always been on a 2.3.x release.

                                          A confirmed solution would be really helpful.

                                            @Veldkornet:

                                            …
                                            The below does indeed work once off, so I need to run it every time I change the configuration.

                                            mkdir /var/unbound/test/
                                            cp -ax /var/unbound/*.{key,pem} /var/unbound/test/
                                            

                                            Is there a bug logged for it already?

                                            works for me.
