RDP to windows server 2016 not working google cloud platform

My windows server 2016 is not connecting using RDP. It was working till yesterday but today it is not working. I had just rebooted the server and no other change was done. I am able to connect using Interactive Serial Console. Following are the findings:

  1. Faulty server is not reachable from any other working server in the same subnet. Neither ICMP (ping) nor with TCP. For TCP, I checked with Test-NetConnection -Port 3389 and result was a failure.
  2. Surprisingly, The faulty server is able to reach other servers with ping and Test-NetConnection on port 3389.
  3. RDP is in running state. Verified by sc query SessionEnv, sc query TermService, sc query UmRdpService, sc query RpcSs, sc query RpcEptMapper. All these services are running. Also, restarted services.
  4. Netstat -a shows that RDP is listening on port 3389.
netstat -a | findstr 3389
  TCP    0.0.0.0:3389           IPADDRESS:0       LISTENING
  TCP    [::]:3389              IPADDRESS:0       LISTENING                
  UDP    0.0.0.0:3389           *:*
  UDP    [::]:3389              *:*
  1. Verified No antivirus, windows firewall, security blockage.
  2. Followed the steps given on https://cloud.google.com/compute/docs/troubleshooting/troubleshooting-rdp and output is PASSED. For NLA and SecureLayer the output was different and added the required changes to registry.

Can someone please help me to fix this? Is it possible to verify if RDP is broken?
