Correct Setup with www. for multiple sub domains and ips

[JulianDev]

Hello,

I think my DNS records are not really the best.
I have 1 domain wich has 3 Subdomains.
Every subdomain is leading to a seperated ip.
My problem is now i dont know how to add the www. in front of any domain.

I searched along but didnt find anything regarding subdomains, www and multiple ips

Ah…you may be running into this:

Subdomain too deep

This tutorial covers a possible reason for the SSL_ERROR_NO_CYPHER_OVERLAP and ERR_SSL_VERSION_OR_CIPHER_MISMATCH errors (Firefox and Chrome respectively) when seen on a subdomain. The Cloudflare universal certificates cover example.com and *.example.com. This means that it covers any subdomain one level below the domain you signed up with. It will cover www.example.com and subdomain.example.com, as these are one level below the root domain, example.com. The certificate will not cover www.sub…

So…you can add www in front of a subdomain, but Cloudflare’s Free Universal SSL won’t cover it.
