This domain is NOT on Cloudflare, so Cloudflare cannot handle SSL/HTTPS for it.
You need to add the domain to your Cloudflare account first… just as you did for yakimabranding.com… before Cloudflare can manage certificates for the domain.
Then set a redirect from yb.marketing to www.yakimabranding.com (the canonical domain).
In any case, https://yb.marketing already shows ERR_CERT_AUTHORITY_INVALID because you’re using Cloudflare’s Origin Certificate for a domain that’s not proxied on Cloudflare.
