Hi,
WS_E_SERVER_REQUIRES_NEGOTIATE_AUTH error could be returned when the remote endpoint did not accept the HTTP header authentication scheme chosen by the client and instead requires negotiate authentication.
And as the similar thread which you posted said, in order to complete certificate enrollment, the Web site for the CA must be configured to use HTTPS authentication, so please check if you configure it correctly, you could also follow the article as below to try:
Active Directory Certificate Services (AD CS): Error: "In order to complete certificate enrollment, the Web site for the CA must be configured to use HTTPS authentication"
