Website does not open with www or https:// prefix

Hello, my subdomain cannot open with the www or https:// prefixes.

Is there a way to solve this problem?

I got a message from Google explaining that the site must be opening with the www or https:// prefix.

We will need to know your domain name in order to offer any useful answers.

Hello, thanks for your reply.

The domain is automotohistory DOT com, it can open with both www. & https:// prefixes.

It is protected by the Let’s Encrypt certificate.

The subdomain is parts DOT automotohistory DOT com (it can only open after typing the name of the subdomain). It can’t open with both www. & https:// prefixes.

I tried to add the following records to the Cloudflare settings:

acme-challenge.parts.automotohistory.com TXT nvDC67IVRKuVZGgI8i2X-F5ZEOePlPK_DFnQija0tpQ

name www.parts & content parts.automotohistory.com

Nothing seemed to work…

Note that the TLS/SLS mode is set to FULL.

Thanks for sharing the domain name. You are trying to proxy a hostname that is deeper than Cloudflare provides certificates for without a paid add-on.

Universal SSL certificates only support SSL for the root or first-level subdomains

See the following:

Always use Full (strict) and not Full or you risk invalid certificates being accepted.
