Cannot update Burp

Heijstek, | Last updated: Jun 05, 2020 12:04PM UTC

Recently I seem unable to update Burp, or any of the extensions in the BaApp Store. My employer has deployed proxy settings, but due to COVID19 I'm working from home and with Firefox configured to use Burp as proxy, I'm able to browse all the sites I want. I've checked the certificate settings, those were correct, and I tried to access https://portswigger.net/bappstore/currentlist with Firefox while using Burp and I could successfully download the currentlist file. Yet I when I click on Refresh List button in the Extender tab, I get the notification "Failed to update BApp list" Is there some setting I configured incorrectly?

Could you try issuing GET /bappstore/currentlist HTTP/1.1 Host: portswigger.net from repeater, with a target of "portswigger.net" on port 443 (and the use HTTPS checkbox ticked)? Do you receive a 200 OK response? If you are using a proxy, have you tried configuring an upstream proxy in Burp's User options?

I'm not getting a response through the use of the Repeater, which is strange, as when I use Firefox with Burp I can reach portswigger.net/bappstore/currentlist I've also tried the upstream proxy, but that did not work.

Nevermind, I've found that it's the corporate McAfee Proxy who's being a pain in the ass. With a own proxy it works as intended.
