Question PS4 NAT Type FAILED

[R3sist]

When i am trying to connect or set up my wifi connection on my ps4 it says NAT TYPE FAILED. It never happened before. Due to this I couldn’t use the network features properly amd I cannot join parties at all. I tried connecting it with another wifi and it works fine but it doesn’t with my primary connection. It has never happened before and I don’t know the reason as to why this happened. Please HELP!

What is your primary connection?

I use an AIRTEL BROADBAND which is an Indian comapny. The plan is of about 300 mbps up and down.
