does anybody listen on 443?
SSTP fails:

  • DO NOT SETUP IIS binding on port 443
  • DO NOT setup Remote Desktop Terminal Services gateway on the same Machine


netstat -a | find /I "443"
  TCP    0.0.0.0:443            VMxxx:0                LISTENING
  TCP    [::]:443               VMxxx:0                LISTENING
if you dont get similar output you may have problem on ther listener for sstp.

delete sstp urlacl:
netsh http delete urlacl http://+:443/sra_{BA195980-CD49-458b-9E23-C84EE0ADCD75}/

restart services / and/or reboot =>
