Request Terminology Sync Task Error

The request terminology sync task is currently producing this error: 

ERROR #6248: SOAP response is a SOAP fault: faultcode=wsse:FailedAuthentication
faultstring=The security token could not be authenticated or authorized
faultactor=
detail=

The task is running correctly on other edges. I checked the HS_Services password and its the same as on the other edges. Anyone has any thoughts as to what could be causing this and how I can fix it.
