Can't connect to Mikrotik PPTP Server

Hi all,

I have a PPTP Server on my Mikrotik board (RB2011UiAS), almost all users connect using Windows PPTP client. The most of times everything is fine and everything works as supposed to but from time to time some users can’t connect to my PPTP Server, Windows gives them Error: 806. I manage to “fix” this issue by rebooting Mikrotik, after reboot the user connects without a problem. I would like to understand why does this happen and how to fix this issue permanently. Thank you in advance.
I’m using RouterOS: 6.9

Below is a print screen of the error and the log from mikrotik:

Anybody?

update routerOS?

I’ve got the same problem in 6.20.

Did you ever figure it out?

I just got a request for MT as a VPN, trying to get it going and I find that the documentation on RouterOS is severely lacking as far as VPN config goes.

Bump…

Looking for an answer also…
