Subdomain troubles

Hi Tom! Thanks for the tip.
I did the set up on my web hoster.
They said to set it up as A type.
Now I get a secure connection error though.

Secure Connection Failed

An error occurred during a connection to www.illustration.elgatoproductions.net. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

How to solve this?
