[Pdns-users] Problems with domain XFR after certain TXT records added

I have a customer that recently requested a TXT record to be added to their zone and our NOC staff obliged, however it was noticed that after that record was put in place domain transfers would no longer go through. I have included the record data below for troubleshooting purposes as well as responses I am getting when the record is put in place.

Record data is : "k=rsa\; p=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANN7f35vhf6vGk1OuqKwe1Dq0l2jg+b8LP0cGBlL8jvtHjLJ0eWB8lvbEyOgcrS0rcLZV0GIYolzhGA/q2B7N50CAwEAAQ=="

Whenever an AXFR is run from an allowed IP it returns the following, as though the connection was denied:

dig @ns1.host.net newsmax.com AXFR
;; Connection to 2001:5b8:1::1#53(2001:5b8:1::1) for newsmax.com failed: permission denied.

; <<>> DiG 9.5.0-P2 <<>> @ns1.host.net newsmax.com AXFR
; (2 servers found)
;; global options:  printcmd
newsmax.com.            3600    IN      SOA     ns1.host.net. root.host.net. 2009022200 10800 3600 604800 3600
;; communications error to end of file

However, when that 1 record is removed everything functions as normal. I am at a complete loss as to what in this record data could be causing this strange behavior, any ideas?
