Not able to intercept specific HTTPS traffic

sonal | Last updated: May 10, 2018 08:44AM UTC

Hello, I am not able to intercept the HTTPS traffic using burp. I have installed certificate. I able to intercept the https://www.google.com but not able to intercept one specific URL. When i set the proxy, URL main page itself is not loading.

It sounds like your certificate hasn't installed correctly. Have you tried removing and reinstalling the certificate? Which browser are you using? Did you have to click through any warnings to access https://www.google.com? What is the URL you are unable to intercept? If this information is sensitive, you can email us at support@portswigger.net.

Prajakta, what post requests are you trying to intercept? Are you encountering any error messages in Burp?

I am also unable to intercept any https pages like google or facebook after installing a CA certificate. In fact, I am unable to load the pages also. But when I turn off the intercept the page successfully loads without any error

When intercept is turned on, Burp Suite should be intercepting the request. The request should appear in the Proxy "Intercept" tab. Are you able to see the http request in this tab? We have two tutorial pages to help you use Burp Proxy within our Support Center, have you checked these out? - https://support.portswigger.net/customer/portal/articles/1783118-getting-started-with-burp-proxy - https://support.portswigger.net/customer/portal/articles/1783119-using-burp-proxy For new users we also recommend that you follow all of our tutorial articles to gain a better understanding of Burp Suite – https://support.portswigger.net/. Regarding HTTPS, which browser are you using? Could you send a screenshot to support@portswigger.net displaying the certificate installed in the cert authorities tab?

I have followed the instructions given above but I am still unable to intercept traffic despite the CA certificate installed in my firefox browser. Infact with the proxy ON, the https page wouldn't even load.

When intercept is turned on, Burp Suite should be intercepting the request. The page should not load. This is expected behavior. The request should appear in the Proxy "Intercept" tab. Are you able to see the request in this tab?
