RDP Error - Contact Network Administrator

Hi Team,

I am facing the RDP session issues as you can find in my attachments.

 In our environment we take RDP to a  Windows Server 2012 R2 (Jump Server) - connected to our environment Via VPN Tunnel or with Public IP.

The Jump server is connected to another 3 Servers in different location (datacenter) via VPN Tunnel. So first we take remote to Jump server and from there we take remote to other 3 Servers in different location.

But right now we are having issues with RDP when we take from Jump Servers to Other 3 servers. I am getting the errors as per the attachment.

Steps Taken:

ON JUMP Server

1. Check Telnet to other 3 servers for 3389 - Working
2. Tried to take remote with Others Users - Didn't connect
3. Updated some windows patches and Restarted the Server.
4. Even created a new User on 3 servers and tried to take remote from JUMP - Not working.
5. Tried to take remote to other local servers(Same Jump server environment)  - Working.
6. Verified VPN Tunnel Connectivity also from firewall level.

ON 3 Remote servers

1. Server Still working.
2. They can able to Login with same users from local .

Please help me to resolve this issue .

Thanks in Advance

Regards,
