Managed WordPress site can’t provide a secure connection?

Hello,

I just purchased a "Managed Wordpress" hosting package as of today. I installed the default template. When I tried to access the website to see how it looks, I get this:

 

This site can’t provide a secure connection

www.az337.com uses an unsupported protocol.

ERR_SSL_VERSION_OR_CIPHER_MISMATCH
 
Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite. This is likely to be caused when the server needs RC4, which is no longer considered secure.
 
Can someone please explain this issue to me, and what I need to do to correct it??
Thanks in advance.
