Private PPTP VPN connection failed

Post by ramseslegrand75 »

I build a VPN server with pptpd on a Raspberry.
I use this VPN from an other place on a PC(LinuxMint 18.2 Cinnamon 64 bits) and on some others Android devices.
With Android everything run fine. The syslog from the server when I connect and disconnect with Android:

Of course my question is: how to connect the PC, is something wrong in the parameters inside networkmanager ?
Something else: everything worked with LinuxMint 17 !
Thanks for help
