Can't connect to VPN

Hello,

I am trying to configure my VPN. I installed openvpn and networkmanager-openvpn and configured everything correctly in Network Settings of my Cinnamon DE,
and when I try to connect by clicking the switch ON beside the created vpn connection, in the nm-applet, nothing happens: it refuses to switch on the connection
without any warnings. Also, I get no warnings at all in terminal. What is the problem and how can I connect to my VPN through some other app, if this is bug in nm-applet?

Thanks in advance.

EDIT: when I try to connect manually:

sudo pptpsetup --create foo --server foo.bar --username foo --password bar --encrypt

I get:

/usr/bin/pptpsetup: couldn't find MPPE support in kernel.

I installed ppp-mppe from AUR and replaced ppp because it interconficted with ppp, but still nothing happens.

EDIT (2) OK, seems that I did some progress here: I installed networkmaanager-pptp and pptp-client,
rebooted the system and now I can connect to the VPN, but when I turn it ON, it says connected but
can't ping a single address, hm... Also tried adding VPN's DNS nameservers to resolv.conf, still no success:
it says "connecting to VPN" for about 30 seconds, an then just gives up...

I don't know if I need to modprobe tun, but when I try to, it doesn't say anything and lsmod doesn't find tun at all,
although there is a tun.ko module in /lib/modules/XYZ...

In Windows, it connects just fine. What I am doing wrong or missing?

EDIT (XYZ) YATTA!! I did it!! :-)))))
The problem was VPN DNS nameservers, when I entered them to resolv.conf, it got erased and replaced by nm-applet, obviously.
I managed to connect through terminal:

$  sudo openvpn --config MyVPN.ovpn

Q: This is really weird: I can connect perfectly with openvpn command from terminal, but it doesn't connect through networkmanager applet.
Is there any way I could automate connecting through VPN at boot or however and how can I avoid erasing my resolv.conf when connecting WiFi?

Re: Can't connect to VPN

Sorry to bump an old thread, but I was having the same issue in Cinnamon 2.2.16 with NetworkManager 0.9.10.0-4. When trying to connect to a PrivateInternetAccess VPN server, I wasn't able to switch the connection in the applet to "ON", nor could I connect via terminal, until I disabled the dhcpcd services and rebooted.

systemctl disable dhcpcd
systemctl disable dhcpcd@

This allowed me to connect to switch the connection "ON" or connect via terminal. However, I wasn't able to ping anything or access any sites, and had to go back to edit the DNS servers of my VPN connection in NetworkManager or /etc/NetworkManager/system-connections.
