I am working on rolling out DUO and have come into a bit of an issue. I installed the DUO application on a Windows Server 2012R2 server (physical machine), enabled only for RDP connections. When I attempt to RDP into the server I get the following error “Bad Request Timestamp () [40105 Error]”. The network I am testing in is not in a domain, but in a workgroup. Here are the steps that I have taken so far:
- Ensured I has .NET 4.5 installed.
- Made sure time settings (NTP) were all good.
- Checked to make sure Windows Firewall and any other security software(s) were not blocking traffic between DUO and my network.
- Ensured the server has connection outside of the internal network.
5, Also double checked username on the machine, to make sure it matched what is in DUO.
Has anyone else encountered this issue? If so, how did you resolve the issue?
Thank you in advance!
