Thanks for your message. One thing I can see from the details you've posted is that the CN for your wildcard certificate is *.xx whereas the collaborator server domain is collaborator.xx. Can you double-check the details for the wildcard certificate to see if it matches the Collaborator domain for me in case this has just got out of sync as you've been preparing the information to post publicly, please? If you do want to share more detailed information with us directly feel free to email support@portswigger.net.

I see that the DST root cert is expired, I have disabled this certificate in /etc/ca-certificates.conf like suggested on stackoverflow: https://stackoverflow.com/questions/69408776/how-to-force-older-debian-to-forget-about-dst-root-ca-x3-expiration-and-use-isrg but the issue persists.

Thanks for the update. Would you be happy to email us a copy of the configuration file so we can double-check the details and run some tests on it here, please? It would be useful to see the actual file, just in case some of the syntax or characters have got changed as they've been copied into the forum. If you can email it to support@portswigger.net and reference this forum post that would be great :)

Thanks :) We don't seem to have received your email yet I'm afraid, would you mind resending it, please?

Maciej | Last updated: May 26, 2022 09:56AM UTC

I have resent again, I tried to send you the tar with letsencrypt certs too just in case but your email gw has rejected it because of securityaay.

Michelle, PortSwigger Agent | Last updated: May 26, 2022 12:44PM UTC

Thanks :) We've got your email, it just has the collaborator config file attached but that should be enough for now, we'll take a look through it and be in touch soon.
