Please select your Product & Server Software Vendor to view detailed instructions
for generating a CSR. If your server is not listed or you need additional information,
refer to your server documentation or contact your server vendor.
- Check the common name field. You may have specified an IP address (e.g. 18.104.22.168)
or a server name (e.g. mywebserver) instead of a Fully Qualified Domain Name such
as www.mydomain.com or domain name such as mydomain.com. You must specify a Fully
Qualified Domain Name or domain name to enroll for a RapidSSL, FreeSSL or Professional
- Make sure you do not have any illegal characters in any of the fields in the CSR.
Illegal characters are [! @ # $ % ^ ( ) ~ ? > < & / \ , . " ']
- Check the country field. If you are located in the United Kingdom, do not specify
your country code when generating the CSR as "UK" - it must be "GB".
- Make sure you have included the header and footer of the CSR into the enrollment
form. The header and footer will look like:
-----BEGIN CERTIFICATE REQUEST-----
-----END CERTIFICATE REQUEST-----
Make sure that there are 5 dashes on each side of Begin and End certificate request.
There should also be no trailing spaces in the CSR.
