In my Apache error.log, I am getting an error like the following:

Hostname www.example.com provided via SNI and hostname hk.dv.nextmedia.com provided via HTTP are different

I have no idea what hk.dv.nextmedia.com is. It is not related to my website or server and I have never entered that domain anywhere in my Apache or server configuration.

Can anyone shed some light on this error? Should I be worried about anything malicious that may have happened on my server?

This is a client-side error or someone probing for vulnerabilities.

"a client indicates which hostname it is attempting to connect to at the start of the handshaking process" https://en.wikipedia.org/wiki/Server_Name_Indication
