Got the issue report from our customer in Mar/2021 which is generated by Nessus ( Vulnerability Management Solution for Modern IT | Tenable.io® ) that sounds similar to SSL Certificate Cannot Be Trusted posted in Oct/2020 from the description:
We are working on a solution to this issue in the future
Wondering if there is any progress update that can be shared with us?
The following certificates were part of the certificate chain sent by the remote host, but they have invalid OCSPResponse signatures : |-Subject : C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=COMODO ECC Domain Validation Secure Server CA 2 |-OCSP Signature : Decryption Failed |-Subject : CN=ssl910119.cloudflaressl.com |-OCSP Signature : Decryption Failed
The below is the list of docs we quickly walked through but failed to find out anything new.
