RDS Certificate Mismatch error

Hello,

We have a 2012R2 RDS farm with 3 session hosts.

DNS farm name = farm.domain.local

Session hosts = ts1.domain.local, ts2.domain.local, ts3.domain.local

I have created a SAN cert and it is issued to farm.domain.local from our internal CA. We are not exposing this farm to external users.

All 3 session hosts servers fqdns are listed under the subject alternative name section of the cert.

When I RDP to farm.domain.local I receive a name mismatch error

Name requested = farm.domain.local

Name in certificate from remote computer = ts1.domain.local

If I click view certificate I can see the name of the session host server listed in the SAN details.

Any assistance would be greatly appreciated
