Attach public (.cer) certificate

Hi All,

We are setting up a government based website that sits on a subdomain (e.g. and I have had the domain in CF modified to a CNAME setup and the TXT record is now verified.

I have been given an SSL certificate in the form of a public .cer file (i.e. no password or .pfx) and I don’t seem to be able to see how or where I can attach the certificate to the domain.

Thanks for your help,

Only Business and Enterprise plans let you use your own SSL certificate.


Thanks for the reply. We are on a business plan currently.

I have gone into the Upload Custom SSL certificate and key page, but that is expecting a key which I don’t have.


You definitely need the Private Key as well as the Public Key.
