Great that you looked over it, have tested it again and the kdig report
differs which looks now like this:

;; DEBUG: Querying for owner(google.com.), class(1), type(1),
server(81.3.27.54), port(853), protocol(TCP)
;; DEBUG: TLS, imported 128 certificates from '/etc/ssl/certs/ca-
bundle.crt'
;; DEBUG: TLS, received certificate hierarchy:

;; DEBUG: TLS, skipping certificate PIN check
;; DEBUG: TLS, The certificate is NOT trusted. The certificate requires
the server to include an OCSP status in its response, but the OCSP
status is missing. 
;; WARNING: TLS, handshake failed (Error in the certificate.)
;; WARNING: failed to query server 81.3.27.54(a)853(TCP)

Exit status: 0

May this is helpful for you.

Best,

Erik
