I hope this is the right place to ask. I have a Galaxy S8 and until a couple of days ago was working fine, but now when I go to my Connections in the settings tabs, and check that I'm connected to the wi-fi, my router name is there at the top, but underneath it says Authentication error occured. It keeps trying to connect but no luck. I have tried switching the flight mode on and off again as mentioned in a previous community post, but no luck. Can anyone help please?
