This error messgae is typically shown when the field "COMMON NAME" inside the CSR doesn't have a valid value.
You can use our online CSR decoder available under https://www.interssl.com/de/ssl-tools-csrdecode.php to decode your CSR and check the fields. - A typical valid CSR looks like this:
Country: AT State: Tyrol City: Absam Organisation: Baumgartner New Media GmbH Common Name (Domain): www.interssl.com Email:
It's important that the field "COMMON NAME" is showing the fully qualified domain name (FQDN) for which the SSL certificate will be issued. - For wildcard SSL certificates you have to use the asterisk wildcard placeholder instead of the subdomains, e.g. *.interssl.com
In case you can't resolve the issue, please open a support ticket. Our experienced team will be happy to assist you!
