Can not connect to the server after start the sstp-server by systemd

[reee]

The server OS is Centos 7, I copy the .service file from archlinux aur which is written by you.
Use this .service file i can start the sstp server . but when i try to connect. the /var/log/message shows:

Feb  4 03:41:18 test pppd[6582]: Couldn't open the /dev/ppp device: No such file or directory
Feb  4 03:41:18 test pppd[6582]: You need to create the /dev/ppp device node by#012executing the following command as root:#012#011mknod /dev/ppp c 108 0

and the connection fail

I try to create the file manually. But do not fix this problem...
