Your PC can't connect to the remote PC because your PC or device did not meet the Network Access Protection requirements set by your network administrator, for one of the following reasons:

1) The Remote Desktop Gateway server name and the server's public key certificate subject name do not match.
2) The certificate has expired or has been revoked.
3) The certificate root authority does not trust the certificate.
4) The certificate key extension does not support encryption.
5) Your PC cannot verify the certificate revocation list.

Contact your network administrator for assistance.
