Just had an old RB951-2n die and replaced with a new RB951Ui-2HnD.
As the old board was dead, I only had an old version of the config.
The new router is showing the following problem.
I’ve created self signed certificates and have a working SSTP VPN using a PPP secret, however, using a RADIUS login it fails with a 734 error on the Windows client and “encryption negotiation rejected” error in the log.
If I change the RADIUS secret or enter the wrong password, I get an authentication error in the log and a password error on the client, so I’m fairly certain that the issue is not to do with the user account.
Any suggestion as to why it is not connecting with a RADIUS login?
