Reissuing a certificate is basically another word for reinstalling. You can only reissue a certificate for the same Fully Qualified Domain Name (FQDN) and you cannot change the domain in any way. Reissue a certificate is appropriate when you change hosting server location, if something goes wrong during or after the setup if you want to change the algorithm, or you simply want to reinstall it.
You can reissue a certificate as many times as you want, but doing it repeatedly may raise certain suspicions which, in turn, may result in the completion of validations and verification of ownership.
Before we start we want to be prepared and generate the CSR since this will be used during the setup. Please see this guide on how to Generate a CSR with name.com. If you have hosting with another provider, you would need to generate the CSR with them, as well as contact them for any assistance with this process.
Once you have a good CSR, please submit a ticket at https://www.name.com/support/sslticket with the new CSR for us and we will reissue the certificate.
Your CRT certificate will be emailed to the same email address shortly. For instructions on how to apply the CRT to our hosting, please see this guide, and it will conclude the setup. If you have hosting with another provider, you would need to install the CRT with them or supply them with the CRT and they can install it as well assist further.
