I am having troubles with installing certificates in Sophos XG Home. Ultimately, I would prefer to setup and install my own CAs(root and intermediate) and use certificate from my own CAs for the web interfaces and for SSL inspection. I setup the root and an intermediate CA, issued a certificate for the firewall, and uploaded the certificate and configured my CAs in the CAs section, as well. But the certificate is shown as not trusted. After a few attempts(including making sure the entire trust chain was included in the certificate file), I decided to simply use a Let's Encrypt certificate to at least get the web interface using a proper certificate. However, even the Let's Encrypt certificate didn't show as trusted. After a few attempts and searching discussions, I discovered there were recent(a few months back) issues with Let's Encrypt certificates. Even though these issues have supposedly been fixed, I decided to try a cert from a different CA. I tried a got a certificate from ZeroSSL, and I am having the same issues: I can install certificates, but they are never trusted by the firewall.
Is there something that I am missing?
