Thank you for posting your question on Microsoft Q&A.
Based on the information you provided, it appears that AFD is treating the certificate you generated as a self-signed certificate, even though it was issued by OnecertV2-PrivateCA.
1.To confirm whether the certificate is self-signed, please check the issuer and subject values. If both values match, then the certificate is indeed self-signed. Need to create private certificate.
2.Also, it might be the root CA certificates are self-signed. To resolve this issue, you may need to add the CA to your trusted CA list. Here is a document that explains how to do this: https://ubuntu.com/server/docs/install-a-root-ca-certificate-in-the-trust-storethen try to add the certificate in AFD
Hope this helps. Do let us know if you any further queries.
