SSTP: bad peer version

I have an issue with SSTP tunnel between 2 mikrotiks failing, the error is “bad peer version”. It seems to come up under load.


Any ideas?

I get it quite a bit with ~140 SSTP clients on my RB1000. Typically requires stopping and starting the SSTP server to get it going again.

Using certificates on both ends of the connections and RADIUS to authenticate/hand out IPs. All Mikrotik clients. 5.0 beta 3,4,5,6,RC1,2,3 and trying 4 right now.
