I've moved your post to the "Help" category. If you'd created it here, you would've seen the following questionnaire. Please fill out the questions below - what you've provided isn't enough for anyone to provide meaningful help. That error simply means that you're attempting to load a name that's not on the certificate. Thus, the "My domain is" question is the most important.
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help.
