"This hostname is not covered by a certificate." Cloudflare recommending: "purchase Advanced Certificate Manager to use Total TLS for full certificate coverage of proxied hostnames."

Describe the bug Everything seems to be working (IPv4 is being updated on Cloudflare automagically). However, when DNS update is handled by cloudflare-ddns the entry made has a warning icon next to it and the following error message:

This hostname is not covered by a certificate. To ensure full coverage, purchase Advanced Certificate Manager to use Total TLS for full certificate coverage of proxied hostnames.

When I manually select Add Record and create the DNS entry on my own this warning does not show up at all.

Error messages To help avoid ERR_SSL_VERSION_OR_CIPHER_MISMATCH errors, Cloudflare automatically shows an error message - This hostname is not covered by a certificate - on proxied DNS records not covered by a TLS certificate.
