  Sound more like a DNS problem. What to Ping or TRACERT report?

  There are no bugs - only undocumented features.

  Ping & tracert did not show any problems. After searching on the issue I think it is related to SPN, something I don't know much about! I will get back with the solution.

  From the event viewer:
  The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server xxxxx_Service. The target name used was HTTP/xxx-xxx.xxx.xx. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Ensure that the target SPN is only registered on the account used by the server. This error can also happen if the target service account password is different than what is configured on the Kerberos Key Distribution Center for that target service. Ensure that the service on the server and the KDC are both configured to use the same password. If the server name is not fully qualified, and the target domain (xxx.xx) is different from the client domain (xxx.xx), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server.

  This spn command did the trick :-)
  
  setspn -s http/full comp. name Domain\NAV service User
