Answer 1

15:51:17 pptp,ppp,info,account android logged in, 0.0.0.0

I'm expecting to see the client's ip here, not 0.0.0.0. Moreover, the ip that was internal was allocated to the client.
And since there are zeros, the root of the problem is worth looking for
1) ppp profile, specifically local&remote address. Most likely the pool for users is not selected.
2) User profile, invalid ppp profile specified.
Well, in the appendage it is worth including extended logging during debugging. There are many interesting things.
