Client VPN issue

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.

Re: Client VPN issue

I deleted the connection and went through the same steps of creating another Client VPN tunnel and it worked.

I had the VPN tunnel set up for quite awhile now, then today it stopped working.

Re: Client VPN issue

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.

Re: Client VPN issue

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.

Re: Client VPN issue

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 Smiley Happy
