The server certificate is not valid because the public key of the certificate contains an object identifier (also known as OID) of 2.5.29.15, but does not support the Extended Key Usage (EKU) for encryption. For the "Request clients to send a statement of health" setting that is enabled on this RD Gateway server to function, if the certificate that you plan to use contains an OID of 2.5.29.15, you must ensure that one of the following key usage values for this certificate is also set: (1) CERT_KEY_ENCIPHERMENT_KEY_USAGE (2) CERT_KEY_AGREEMENT_KEY_USAGE (3) CERT_DATA_ENCIPHERMENT_KEY_USAGE. For more information, see "Obtain a certificate for the RD Gateway server" in the RD Gateway Help.
