Hi all,
We are testing a higher encryption and our mac users can connect but our windows users error our getting the "L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations" notification. We are running windows 10 pro 64 bit. I have tried https://documentation.meraki.com/MX/Client_VPN/Troubleshooting_Client_VPN but no dice. IKEEXT service is running, the firewall can't be blocking it because mac users can connect, and I have tried a few times to re-enter the passphrase. I have also tried rasphone but this gets the same error. Any help would be appreciated.
