Troubleshooting

1
Symptom: Cannot reach server by name
  • Cause: Windows 11 does not resolv the internal servername over an IPSEC VPN-connection, for example \\KLANT-1A
  • Solution: This can be resolved on your PC by changing the settings of your "VPN-adapter", see the instructions in "Configure"
  • Workaround: Your 1A-server can also be reached on the "Server IP-address" that you can find in server-info
