error code 6003

[rackey12]

i have followed your steps and i did have a few errors that you fault finding help resolve now when i run the ddclient -daemon=0 -debug -verbose -noquit i get the following error

RECEIVE: {"success":false,"errors":[{"code":6003,"message":"Invalid request headers","error_chain":[{"code":6105,"message":"Invalid Content-Type header, valid values are application/json,multipart/form-data"}]}],"messages":[],"result":null}

and i am not sure what i am doing wrong, i have double checked the config ddclient.conf and all seams to be correct there the zone is my domain and username is my email password is my globel API Key and the domain to update again is my domain.

any help would be appreciated
