NAT Type failed on PS4

Did your JioFiber ONU recently got updated?
While it's true due to CGNAT you won't get port forwarding, I believe you should get at least Type3.
Check if UPNP is enabled and try again. If it does not work, add a static IP for your PS4 and put it in DMZ.
You are just using the JioFiber router, right? No other shenanigans?
 
@Lolita_Magnum I think it did get updated. I enabled UPNP myself. I donot know how to add a static IP for my PS4, could you tell me or link me to a guide? I'm using the JioFiber router with a LAN cable attached to my ps4. There is also another router connected to the JioFiber router as an extender.
