"Router disconnected" error in webfig over SSTP VPN

RouterOS General
1

Hi,
I have RB750GL firmware with configured SSTP VPN.

  • I can connect to VPN fine and connection to LAN is stable.

  • But when I open Mikrotik webfig I can only login. If I move mouse over any button, or click anything I’ll get error “Router disconnected” and I need to login again.

  • SSTP connection is not terminated - just admin session to Mikrotik webfig.

  • I have also configured proxy arp on LAN interface as described in the guide (http://wiki.mikrotik.com/wiki/Manual:Interface/SSTP)
    /interface ethernet set ether2 arp=proxy-arp

Any settings that I’m missing?

RouterOS version is 6.7.
