Can someone explain to me why I can not access a webpage while intercepting with BurpSuite? When turning off the interception everything works fine and I can see the traffic in the http history section. But when turning interception on, the webpages are not loading.
I therefore ask for an explanation to understand this please.
The web page is not loading because Burp has intercepted the request and is awaiting action.

Step 2: Intercept a request
Using Burp's browser, try to visit https://portswigger.net and observe that the site doesn't load. Burp Proxy has intercepted the HTTP request that was issued by the browser before it could reach the server. You can see this intercepted request on the Proxy > Intercept tab.
