When we open a web browser to access a website, a series of background actions are carried out in the background that allow all communication processes to be executed correctly, this includes services, protocols and special connections but we can get to see an error indicating that the connection has been interrupted: the connection has been interrupted a network change has been detected. If this happens, we will not be able to access the web pages we want regularly and we will have problems with the network..
This network connection problem will prevent the website from opening, so we can try to update the site or check in another browser to see if the site opens and thereby verify that the error is not from the connection itself but from the website. If not, TechnoWikis has a series of solutions to correct this error.
