Why can't my cell phone connect to Wi-Fi?

Dear Community,

Today I had no internet at home for about 10 minutes. My cell phone and my laptop were disconnected. After 10 minutes the Wi-Fi was back and my laptop reconnected without any problems.

Unfortunately, it still doesn't work with my cell phone. I restarted both the phone and the router. The network is visible, but when I click "Connect" I see the error message "Couldn't connect".

When I try to connect to other networks, I have this option (if I could get the passwords from my neighbors' networks, I could theoretically connect).

I'm with 1&1. My phone is Xiaomi A2 Light.

Do you have any ideas why this could be?

Do you have any ideas why this could be?

No, not without the corresponding error messages from the router's log files.

Log in with the browser on the surface of the router and take a look there in the error log files, what is there why the connection with the mobile phone has not been established.

Thanks! Somehow I found the option to re-enter the password. Then the connection was established.
