Cannot connect using duo ADFS Application anymore.
I get the error message in windows event logs:
DuoAdfsAdapter::BeginAuthentication called
User from claim: ‘DOMAIN\username’
Duo username: DOMAIN\username UseUpnUsername: False
Duo is unhealthy, invoking failmode.
Microsoft.IdentityServer.Web.Authentication.External.ExternalAuthenticationException: Duo is unavailable: Access Denied
Duo health check failed; failing closed per configuration
I tried creating another application to protect another application but still wont work.
My ADFS config was working fine until it just stopped, No changes made to ADFS or DUO.
Please help…
