      Hi All,
      Hoping someone can help.

      New build pfSense 2.4.4-RELEASE-p3, acme 0.5.8

      I am trying to issue a cert, and keep getting

      dns_request_getresponse: expected a TSIG or SIG(0)
      [Mon Aug 5 15:09:43 UTC 2019] error updating domain

      I have tested using nsupdate via the shell manually, using the keyfile created by the web interface and all works fine. (as indeed does my older pfSense kit running 2.3.4 against the same name server/key etc)

      login.cnet.sgul.ac.uk

        How exactly are you testing from the CLI? You probably need to set the zone parameter, it's blank in your output above.

          Hi,
          Many thnkas for the feedback.

          In the GUI, I have set the Zone section to the correct zone (cnet.sgul.ac.uk)

          acme.PNG

          On the shell on pfSense

          Interestingly, If I omit the "-v" from nsupdate it fails

            More info on this

            It appears accountconf.conf contains an NULL NSUPDATE_ZONE (and is overwritten by dns_nsupdate.sh)

            ACME_DIRECTORY='https://acme-v01.api.letsencrypt.org/directory'
ACCOUNT_EMAIL=xxxxxxxx'
LOG_FILE='/tmp/acme/testing/acme_issuecert.log'
LOG_LEVEL='3'
NSUPDATE_SERVER='login.cnet.sgul.ac.uk'
NSUPDATE_SERVER_PORT=''
NSUPDATE_KEY='/tmp/acme/testing/login.cnet.sgul.ac.uknsupdate_acme-challenge.login.cnet.sgul.ac.uk.key'
NSUPDATE_ZONE=''

            If I set THISNSUPDATE_ZONE at the top of /usr/local/pkg/acme/dnsapi/dns_nsupdate.sh it can issue a cert

              THISNSUPDATE_ZONE

              I've looked for this one before.
              It's used before its initialized, so that explains :

              very well.

              Better yet : can't find "THISNSUPDATE_ZONE" here https://github.com/Neilpang/acme.sh/blob/master/dnsapi/dns_nsupdate.sh

                Are you on the latest version of the ACME package? There was a bug with that a while back IIRC.

                The THISNSUPDATE_<x> stuff is just in pfSense. The stock files from acme.sh don't easily support multiple RFC2136 entries on a single cert the way pfSense uses them.

                  Ah, ok.
                  Have a look at this "THISNSUPDATE_ZONE" in dnsapi/dns_nsupdate.sh - shouldnt it be init (= read) before used and written ?

                    Yeah, I thought it was but I'm not seeing it now, either. I'll look into it.

                      I just pushed a new version of ACME that should fix this. Give it a try when it shows up for you (0.6)

                          Hi there, this still isn't working for me; I've upgraded to 0.6
                          I still see "NSUPDATE_ZONE" as empty and the issue fails. (I know our DNS server needs to have the zone sent for this to work)

                            OK, I missed a couple bits. I just pushed ACME pkg v 0.6.2 which should work now. I didn't test it completely but I did confirm at least that the zone makes it into the account config and logs where it was missing before.
