Every instance in any area around 400 blocks away from spawn, I have tried to build nether portals and activate them, only to be met with a pool of lava and instant death. I have checked Chunkbase ( my world seed is -8578782874118800955 ) and I have checked most of the "estimated nether portals" surrounding up to 600 blocks from my spawn point to no avail. 

I have built a nether portal around X: 72 Z: -424 where there is a Taiga village with a single villager, and that too is met with lava.
