Unable to access labs, getting 404 Not Found

Aakash | Last updated: Aug 14, 2021 06:23PM UTC

Today, I am unable to access labs through burpsuit proxy. Yesterday, I was able to access it without any issues. I tried with chrome and mozilla firefox, Both showing 404-Not Found responses for all labs. My Mozilla Firefox version is "91.0" and chrome version is "92.0.4515.131". It was observed that when I use proxy for chrome/Mozilla and turn on intercept at burpsuit then response shows 404 Not Found. Without proxy at browser, I am getting correct response content.

Hi, I am facing the similar issue. I am using Brave Version 1.34.81 Chromium: 97.0.4692.99 and Firefox 96.0.2 (64-bit). Please help!

Thanks for your mesage. Are you able to access the labs if you use Burp's embedded browser? Can you send some screenshots of the errors you are seeing to support@portswigger.net, please?

Are you able to access the labs if you are not proxying your browser via Burp? Can you email some screenshots showing the labs you have tried to support@portswigger.net, please?
