Www.portal.domain is not working instead of portal.domain

i have a certificate on my website for the ‘www.portal.domain’ site.
some of my users browse also the address: portal.domain site so i have to secure both the addresses via cloud flare, but if activating the could flare for portal.domain it works and i get the cloudflare certificate but if I:
activate the couldflare in www.portal.domain it does not work (This site can’t provide a secure connection
www.portal.domain uses an unsupported protocol. ERR_SSL_VERSION_OR_CIPHER_MISMATCH

If I don’t activate the cloudflare cloud for the www.portal it (obviously) works getting the real certificate on the server, but exposing it…

What should i do to fix the problem?
thank you

if you mean www.portal.domain.com (.com being any top-level domain you have), this isn’t possible due to how TLS works. A wildcard certificate, which is what Cloudflare issues you, only covers one level of subdomains, eg *.example.com covers test.example.com but not abcd.example.com. WWW is a subdomain just like the rest so it has this issue.
