Hi,
We have installed Windows Server 2019 Datacenter and have installed a IKEv2 VPN on this server. This works as hoped until the server reboot's, or more specifically when the service is restarted.
If we tried to connect with a client PC we get "ike authentication credentials are unacceptable", and the only way I can resolve this from what I can tell is to Disable Routing and Remote Access and Configure and Enable Routing and Remote Access
again in the same way each time:
- "Custom Configuration> VPN access"
- "Authentication Methods" > Tick "Allow machine certificate authentication for IKEv2
- "Allow custom IPsec policy for L2TP/IKEv2 connection" (Using a Preshared Key)
- Changing the "SSL Certificate Binding" for one I made
I've also run SFC /SCANNOW and powershell DISM /Online /Cleanup-Image /ScanHealth,none of which helped.
What could be stopping the VPN from continuing to work after the service has restarted?
Kind regards
Adam
