# Images or Scripts Not Loading with Custom Domain (CNAME)

``I get an error message saying that the server could not prove that it is cdn.mysite.com since the security certificate is from *.zapwp.com``

**Error Message: NET::ERR_CERT_COMMON_NAME_INVALID**


# The Solution

The CNAME did not propogate before you linked the account - you can simply reset and re-add it via the plugin as needed! 

|| Feel free to check the CNAME Propogation status at https://www.whatsmydns.net/#CNAME/ (Make sure there are no more red X's before linking!)

DNS Propogation is normal for any newly created domain record or subdomain, it may take up to 48 hours even if properly configured and is outside of our control.

We're happy to help reset or manually renew any certificates via chat support if you need assistance!
