Hi,
I have a problem with my Client VPN. Can someone help me with the troubleshooting this? I was previously able to connect but today when I tried to connect, it gave me the following error.
My event log is as follows.

Kindly let me know what I did wrongly.. 😛
Thanks and appreciated.

Did you by any chance, just install Windows Updates?
I've heard stories about Windows installing updates, that for some reason breaks the L2TP ClientVPN for Meraki. This is a Microsoft thing, not a Meraki issue.
Try deleting the connection again, and setup it up.
Nope i didn't reinstall or upgrade my windows or do any updates.
The day before it was working and suddenly out of a sudden it refused connection.
Have the same issue - the Settings for the Win10 VPN client don't stick - they randomly change to a default value and not the settings needed by the Meraki VPN solution.
Either recheck your existing settings or create a new one using the Meraki instructions as normal.
It's a Windows 10 'feature' used to keep IT teams in a job - lol 🙂

This is happening to our organization now on a daily basis. It appears that the security tab settings on the adapter configuration keep reverting to their defaults. This is incredibly difficult to keep up with. I can't expect all of my users to tweak out their VPN settings all the time.
We noticed that this occurs when Windows installs updates. I confirmed by disabling auto updates and only allowed updates for a small group. Users that were updated were the only ones who reverted.
Hello, old thread but recently had this issue.
Updates do break Win10 VPN Adapter. The workaround is using rasphone.exe. Run from the Search Box and it will pull up your vpn settings. You will know when you are connected by running rasphone again, the "Hang Up" radio button appears..
does anyone know if Meraki support and Microsoft are working on a permanent fix for this? thanks,
I've been using Win 10 VPN client now for a good few months and it's been stable - i've not had to change or update the VPN client settings at all since probably before new year.
Not sure if an Windows 10 update has resolved the problem or what.
