Ps4 NAT TYPE FAILS WHENEVER I TRY TO CONNECT IT TO MY WIFI

When I try to connect or set up my wifi connection on my ps4, it says NAT TYPE FAILED ( when testing the connection) . It had never happened before and I don’t know why this suddenly happened. I tried connecting my ps4 with another wifi ( hotspot of my cellular network) and it worked just fine. So apparently it is only happening with my WIFI. Please help!
