We are aware of instances where websites on Dedicated or Virtual servers running cPanel and/or Cloudlinux are showing the following error;
The client needs a new connection for this request as the requested host name does not match the Server Name Indication (SNI) in use for this connection.`
The issue is caused by recent updates to Apache introduceing stricter SSL/TLS handling (to address CVEs). Further information can be found via the links below.
if you have a managed server with us, we have applied a version lock to prevent updates until a fix is released. For any customers seeing this issue and are unable to resolve, or if your service is managed, please do contact our support team for assistance.
