SSL doesn't work for sub-sub domain

Hi, community!

So I have the main site at and dev version at

Each of them has an admin section set as a subdomain, e.g.: and

So all proxies and SSL work fine except for admin-dev-domain-com.

And I believe it’s because of the sub-sub domain thing, as I found that SSLs don’t support 4th level domain names.

I tried to add dev-domain-com as a separate site to Cloudflare, and it didn’t allow me to do that.

Any solution for this?

Thanks in advance!
