Certificate Not recognized

    Hello!

    Just got my TinyPilot and everything works great, except I can't get the cert to work as expected. I follow all directions for installing the cert on Windows (including placing it in the Trusted Root Certification Authorities), but I still see the same SEC_ERROR_UNKNOWN_ISSUER error. I'm on Windows 11 if that matters. Let me know if you need any other info, and sorry if this ends up being an obvious issue on my side.

    Thanks!

      Hi Adam, thanks for reaching out with your question about certificates.

      The error you are seeing, SEC_ERROR_UNKNOWN_ISSUER, isn't the one that normally appears if the certificate is missing, which suggests that the certificate has been installed but isn't being accepted correctly. I've previously seen this issue when using third-party browsers like Firefox that have additional security restrictions. Would you be able to try testing in a different browser if you have one installed?

          Lol, why didn't I think of this. No issues in Edge (the chrome version). Looks like FF wants me to add the cert too.

          Steps if you'd like to add them to your existing docs:
          Settings >> Privacy & Security >> Scroll down to "Certificates" at the bottom of the page >> View Certificates >> Import the same cert

          Now everything works as expected. Thanks @cghague !

            Thanks for sharing these with us! I'll look into updating our documentation as needed.

            Hii @adam

            While installing the SSL Certificate on Windows, the error SEC_ERROR_UNKNOWN_ISSUER is occurring. It means the browser does not trust the SSL certificate or uses an invalid security certificate, uses a self-signed certificate, or the certificate has been tampered with by a third party. Various methods exist to fix the error and stop getting the warning message. You can look at the detailed article for error solutions at https://cheapsslweb.com/blog/how-to-fix-sec-error-unknown-issuer-error-firefox/.

            I hope it helps!
