I have the exact same problem when I use my android phone to connect to my vpn. The same error messages appear and nothing works. I have to disconnect and reconnect my vpn on my phone to get the connection back. I thought I was the only one getting these messages.

I have pptp vpn set up with default settings, the only thing I have added is the username and password.
 
just tried alpha2 still broken

also tried the latest stock asus firmware for the ac66u exactly the same on that
even went as far as clearing nvram

pptp is broken

odd that no one is commenting on it

The problem is either your client or your configuration, as it's working fine for me.

i have ruled out my config by erasing the nvram
and the client is my Galaxy S3 LTE it has always worked fine

have you tried it on mips devices
maybe its only broken on mips
 
umm

my S3 LTE was recently updated from Android 4.3 to android 4.4.4 (Samsung official)

it seems pptp is broken on it

I just dialed in with a pc and its fine
didnt think for a second to check the phone tbh

There you go.

Most likely reason would be that they didn't enable MPPE support in their kernel.
