Thanks for your message. When you import the Certificate into Chrome, which tab of the dialog are you on? Are you on the "Trusted Root Certification Authorities" tab? There's a screenshot showing what you should see in this article: https://portswigger.net/burp/documentation/desktop/getting-started/proxy-setup/certificate/chrome I hope this helps, please let us know if you have any questions

TLDR: Use the "Authorities" tab in Chrome, not the "Your Certificates" tab. I had this issue as well and I was indeed on the wrong tab. I was on the "Your certificates" tab. This is for "client certificates" i.e. certificates that you own & can use to verify your identity to a server. So it makes sense that you'd need a private key for these! See this answer for more detail: https://superuser.com/a/1276793/656361. Also see here for the difference between client vs. server certs: https://cheapsslsecurity.com/blog/client-certificate-vs-server-certificate-simplifying-the-difference/.
