Hi,
You're going in circles. The certificate has nothing to do with this problem. It's not even remotely relevant, because the kernel never gets to see it and it's not supposed to anyway.
Please check if you have all relevant modules loaded (NOT built at buildtime. Those are two different things.) and please provide the complete log, as shown on the HelpRequests page.
Kind regards
Noel

> You’re right that this kernel is old, it’s Ubuntu 16.04 so I decided to replace that machine with the much newer Debian 9.8. I’m now on kernel version 4.9.0-8-amd64, but this hasn’t helped. I’m actually thinking this might have to do with the certificate I’m using, since the certificate was generated by a Microsoft Certificate Authority, not the internal PKI tools. I created the private key on the Debian machine using the ipsec pki tool, next I generated a certificate request using that same tool and used this request to let my CA issue a certificate.
