I am unable to connect devices via the vpn server (pptp) I have try windows 10, 8, android without succes.
Incoming connection 1723 open in the firewall.
On android I have only failure message, on windows it's "error login or password"
Off course I have verify password, bad typping, try differents accounts, create special account for testing... always "error login or password".
The accounts have off course autorisation to utilise pptp service...
I don't understand where is the problem...
