How to connect android Device to PPTP VPN
Solution 1
thanks to you all but i solve it by checking my pptpd-options file and change
#require-mschap-v2
to require-mschap-v2
#require-mppe-128
to require-mppe-128
i have also change ,removing # like this
refuse-pap
refuse-chap
refuse-mschap
newpeople
update:
And be sure to remove the noauth
option. In his case because it is before the require-mppe-128
and require-mschap-v2
it has no effect but if you still cant make it happen check for noauth
and remove it.
Solution 2
I know this is an old question and this may not be applicable for this case but a simple solution I have found for vpn connection issues on android is to make sure power saving mode is turned off. I looked all over the internet to figure this out and discovered it by accident. Hope it helps someone else. I was using Betternet which is a great VPN service but it would not connect. I turned power saving mode off and it connected instantly.

I have create a PPTP VPN server using ubuntu's guide .
Now I have:
My problem now is that my android phone could not connect to the pptp which I created. When i try to enter the username and password then hit connect , the only message i have is Connecting... but afterwards is Unsuccessful.So I searched and found this link for general overview on how to connect to my PPTP VPN. I also came here but I still cant get my phone connected to the VPN. I have exactly followed what ubuntu's guide is saying, and I don't know now what to do, to achieve my goal. Please give some link or a guide that should I do so that my android phone will be able to connect to my PPTP VPN.
