Hello!! I’ve trying to set up a VPN server on a mikrotik v6.36 following same instructions from multiple websites, but I can’t make it to work.
On macOS logs I can see phase 1 and 2 are succesful, but login process keep showing these errors:

por omisión 14:44:52.180945 +0200 racoon IPSec disconnecting from server
Here’s my config on the router:
L2TP Server: enabled
Authentication: mschap2
Use IPSEC: disabled
Allow fastpath: enabled
Default profile: my-config
my-config profile:
local-address: 192.168.8.1
pool: my-vpn-pool
dns-server: 8.8.8.8
Change TCP MSS: yes
Use PHP: default
Use MPLS: default
Use compression: default
Use Encryption: required
I think everything on the L2TP and IPSec is OK, but something is wrong with authentication 
Thank you!
