EDIT: In Windows 10 or 11, the way to get to the log is as follow:   1. In elevated command prompt, Type: netsh ras set tracing * enabled   2. Try to establish the VPN connection   3.

Without detail log, then the problem could be everyone's guess.   Uninstall WAN Miniport (L2TP) under Device Manager and rescan would be my next guess.   What would be yours?   ... View more

Sounds to me you are on Windows 11 Insider Beta Channel. The version 22000.466 is updated by KB5008353.    The out of band update released by MS is targeted for 22000.438.  I am guessing you will have to roll back KB5008353 first to the target version before you can apply hotfix, or you will have to wait for the next official release.  Since you are on the beta channel, using the provide feedback forum might help.  ...

Microsoft acknowledged the issue. I am not sure if the workaround exist for Meraki MX.   The description is as below:   After installing KB5009543, IP Security (IPSEC) connections which contain a Vendor ID might fail. VPN connections using Layer 2 Tunneling Protocol (L2TP) or IP security Internet Key Exchange (IPSEC IKE) might also be affected.   Workaround: To mitigate the issue for some VPNs, you can disable Vendor ID within the server-side settings. Note: Not all VPN servers have the option to disable Vendor ID from being used.   Next steps: We are presently investigating and will provide an update in an upcoming release.   Affected platforms: Client: Windows 11, version 21H2; Windows 10, version 21H2; Windows 10, version 21H1; Windows 10, version 20H2; Windows 10, version 1909; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSC 2016; Windows 10, version 1607; Windows 10 Enterprise 2015 LTSB Server: Windows Server 2022; Windows Server, version 20H2; Windows Server 2019; Windows Server 2016   Windows 10, version 21H2 | Microsoft Docs ...
