Custom CSR - Common Issues

When you generate a CSR, most server software asks for the following information: common name (e.g., www.domain.com), organization name and location (country, state/province, city/town), key type (typically RSA), and key size. 

If your certificate is getting stuck in "draft" and you are using a custom CSR, then check the following:

  • Please make sure to check that the common name on your CSR is matching the domain name you have entered in the ZeroSSL wizard
  • We only support an RSA key size of 2048 or 3072 bits
  • If you are issuing a wildcard certificate, please make sure your CSR reflects this

In case you are experiencing any of the above issues, please cancel the draft certificate (please see the steps here) and try again.
