Hello,

We need to create a CSR with both CN and SAN fields filled with the same FQDN, because our SSL provider requires the fields to contain that info.  
Its not a wildcard, just a simple domain name.

How can we do that on TH1030S with 2.7.2-P7-SP3(build: 3) ?

Thank you

Hello,

We do not support the functionality where you can fill SAN fields with the A10 box. However, you can use OpenSSL for that functionality.

Thanks,
