When we cannot connect to the computer with the web browser:
It may be that we are in alexa operation mode (in this mode there are no web services).
It may be that we are not properly connected to wifi
If the computer is connected to the router we also need to connect to the router.
If the computer is independent (it is the router, access point) we need to connect directly to the computer.
But it may be that one of the plugins is not configured correctly, causing the computer to find a fault again and again.
The way to solve all the above problems is with the help of restarting the computer in a correct configuration.
