Certificate Error on Connection

Hi,
I am getting certificate warnings when conencting to a VDI desktop via the client, the RDP certs have been issued by my AD CA. I can’t see where to change/make RAS connect using the FQDN of the machine so matches the certificate and does not warn. If I remove the check from use 127.0.0.1 address when using Gateway mode in VPN the client will attempt to connect using the VDI IP address not FQDN.
Any ideas?
