Error 789 - VPN

ozamora1 — Mon, 23 Oct 2023 21:41:11 GMT

Hello all,

Attempting to set up a VPN, used https://documentation.meraki.com/MX/Client_VPN/Client_VPN_OS_Configuration as a reference. I keep getting error 789 and cannot connect to the VPN. This happened on a different laptop as well before but the fix for that was removing "save credentials" for some reason. I've insured that the very specific settings are exact to the laptop that the VPN works on. I've added to the registry with other fixes as well but those didn't help. (UDP & ProhibitIpSec). Installed/unistalled drivers. Turned off firewall. I've the top threads on here regarding this issue and none of those solutions have worked for me.

Any help would be amazing!

789 is classically bad PSK, but it can also pop up when you've got a bad credential OR when Windows has changed the password protocol on you.

Are your users behind the VPN terminating-firewall when they're trying to connect? Because yes, you're going to get weird errors when you do that. You can't connect to the outside when you're inside like that.

For testing, I recommend a hotspot that is 100% not on the same network as your firewall.
