Spaces CDN subdomain with manually generated SSL returns DNS_PROBE_FINISHED_NXDOMAIN

Hi all,

Background Through the App Platform, we have set up a static site with Strapi CMS and DO Spaces for files and images. The domain is hosted on Google Domains but we had delegated it to DO Nameservers and everything was working just fine.

Unfortunately, on the same domain we have our business email and due to garbage level rating of Digitalocean IP’s our email ended up blacklisted on most email platforms.

We have moved control over the domain back to Google Domains and set static site and Strapi CMS with CNAME records. This part works great. As a bonus instantly our emails get clean and out of the blacklist of any kind.

Problem During new set up of CDN subdomain for DO Spaces we have create manually SSL certificat via Let’s Encript certbot - because we are using App Platform and we do not have a place to install certbot for subdomains.

We have add CNAME record in Google Domains for subdomain pointing DO Spaces Orgin. Then we have upload SSL certificate to CDN subdomain in DO Spaces.And now the subdomain returns DNS_PROBE_FINISHED_NXDOMAIN error.

From admin panel we can see that files are added to DO Spaces and both Orgin and Edge links to files works but CDN link returns DNS_PROBE_FINISHED_NXDOMAIN.
