After patching a couple machines with the January Windows Updates I found that our Meraki Client VPN no longer works. I get error 789 in Windows Event Viewer, and nothing at all in the Meraki Event Log. This is the error displayed when attempting to connect. It errors out within a second of hitting connect, doesn't even prompt for creds. We've had AssumeUDPEncapsulationContextOnSendRule set to 2 for some years. I tried removing / rebooting / re-adding this key; same error. I also tried switching our PSK to a key without special characters, same error. I have confirmed this on 2 different machines. Unpatched machines continue to connect without issue. Anyone else run into this today?
