Tried everything but error code is 809 all the time.
Added the registry key as instructed on this website, no luck.
Can someone give a solution to this issue?
My PC windows10 works well but my desktop does not work.
Was there any other client vpn software used before Meraki Client VPN? I have had similar issues with computers that transitioned from Forticlient to Meraki.
IKE and AuthIP IPsec Keying Modules disabled (Windows only)
Solution: This occurs most often when 3rd party VPN software has been installed and disables the IKEEXT service. This can be re-enabled by navigating in Windows to Control Panel > Administrative Tools > Services. Find the service named "IKE and AuthIP IPsec Keying Modules" and open it. Change the Startup type to "Automatic". If this automatically reverts to "Disabled" or fails to start, it may be necessary to remove the 3rd party VPN software:
Look into your Windows error registry
the issue is probably this.
I did fix in this way
I have seen this issue happen with broken NAT implementations in some home routers.
Try this for a test. Turn your Internet router off and back on again. Once you are back onlne again, try the VPN.
Also try checking for any firmware updates for your Internet router.
This issue is hanging for months. I have to use my laptop to connect.
But my router restarts occasionally which does not fix anything as far as i see.
