Security certificate does not specify subject alternative names
This article will guide you on steps to fix #Security certificate does not specify subject alternative names.
Basically, the #error, Security certificate does not specify subject alternative names trigger if the certificate does not have the correct SubjectAlternativeName extension.
Subject Alternative Names or SANs allow you to secure multiple domains from one SAN SSL certificate. SANs are additional domain names added to an SSL certificate.
To add a Subject Alternative Name to a certificate:
1. If you want to add #SAN, most CAs allow you to reissue a certificate with new details, though this will usually revoke your old certificate.
2. You don't need the old CSR to reissue a certificate, you can instead create a new CSR with the updated details using a new or existing private key.
The Subject Alternative Name (#SAN) is an extension to the X. 509 specification that allows users to specify additional host names for a single SSL certificate. The use of the SAN extension is standard practice for #SSL #certificates, and it's on its way to replacing the use of the common name.
