Unknown_ca error, missing detailw

Davide Tampellini Jan 07, 2019 09:15PM UTC


I'm getting an unknown_ca error in the Event log. Sadly I can't find a way to know _which_ host is causing this issue. Is there any extra detail?

This will be an error between your client device and Burp. It won’t be between Burp and the target as Burp doesn’t validate certificates for testing traffic.

Unfortunately there error doesn’t include the IP address of the client. Please check all the clients you’ve configured to proxy through Burp have Burp’s SSL certificate installed.
