Wifi not working

My wifi randomly disconnected so I tried to reconnect it but it was not loading. I reset the network settings which usually works when this happens but when I typed my wifi password in and pressed join, the joint button turns grey and then nothing happens and it doesn’t load. I have restarted my phone multiple times and also reset the network settings multiple times but nothing is working. I have an iPhone XI Pro Max and it’s on 14.0.1.
