PwnBack not working even after troubleshooting

[MiebakaWakama]

Hi,
I might be the only one with this issue so far as I can't seem to find anyone with similar issues on the internet but I haven't been able to get PwnBack to work.

I was able to load up the plugging successfully to burp but couldn't see or generate any traffic even after troubleshooting with the certificate (cacert.pem) provided.

I am on a Kali Linux computer and using the default phantomJs installation but I can't seem to understand what the problem might be.

Thanks
