Connected to mobile hotspot but no internet connection

[ScoobyDude]

As usual when I open my laptop I am automatically connected to my mobile hotspot.
But today when I tried to browse something it shows "Server Not Found".

I can use my cellular data normally in my smartphone.

The last thing I did was ran

Code: Select all

ifconfig -a

Code: Select all

ip a

Before I ran those command I could use the internet

What can I do to make the internet work again? I need it so much
