I have suddently started getting below error for Windows Desktop service, This is not new setup, It has been working fine for few months.

I've already validated below:

1. Teleport CA Certficate is valid and available in LDAP's NTAuth store, even tried importing again.
2. LDAP's CA is valid on Desktop Service instance, also tried to export and use new cert even though they're same.
3. Teleport Certificate is valid and available on all windows machines.
4. Able to validate teleport client certificate(newly generated) on Windows machine.

Teleport Setup:
Multiple Auth and proxy instances running behind proxy.
