I have the below given setting in my web.config of my WCF service, this was working fine till today and suddenly started giving the error "An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail." I have verified the time in my server and client it's same. Any thoughts?
