I just found out today that .app domain names require SSL certs. I purchased it for a DNS redirection to a site that already has SSL cert setup, so my question is if it's possible to set this up?
I am using Google Domains and it's giving me an error when setting a synthetic temporary redirection to my domain name.
This synthetic record has an error and will not function correctly:
The SSL Certificate for this domain hasn't been created yet. This process may take up to 24 hours to complete.
The required link to "https://my-existing-site.com" is not present.
An SSL certificate is missing.
Any ideas?
