If you’ve created a certificate with the wrong address, this article will explain how to rectify the problem.
The certificate generates the site address from the project it's been created in, so to update a site/installation address on a certificate the project site address needs updating then the Certificate will need to be copied.
Locate the Project it's been created in, then click the Settings button next to the Project name.
Then here you can select from existing site addresses or you can click Add new site to create a brand new one.
Once you've done this, locate the certificate and click Options, then Customer Copy.
After the regeneration has happened it will update the site/installation address for you.
