I have followed this guide to the letter https://www.dynu.com/DynamicDNS/IPUpdateClient/PFSense
but I can't get pfsense to update my IP using the "Update all domains in your account" method.
"Bad Authentication" is the error I keep on getting even though my credentials are correct. I have tried my standard pw, an IP update pw and the MD5/SHA256 pw. None work.
