I'm getting 401 access denied captive portal

Hello, I recently got my NetGear NightHawk AX6600. I finished setting it up but when I try to connect to it with my iPhone iPad with Wifi it leads me to the CaptivePortal where I try to login with admin the username google said is default and password which doesn't work. I also try the password I set for my ssid which also does not work. When I tried doing use network without internet access which skips captive portal but keeps you connected I saw that I had internet which is great for my iPhones but my PC and Playstation 5 can't do this. 

Here is a picture of the captive Portal. 

I also tried resetting the password which works then when I try to reconnect to network same thing happens.
