This error indicates that the name provided in the TLS server certificate did not match the server name in the URI.

Things to try:

  * Check that the server is using the correct certificate.

  * Check that the client is using the correct name to connect to the server.  The name must exactly match the name provided in the certificate.  This is usually the fully-qualified domain name, such as ''boot.ipxe.org''.

Note that certificate names are case sensitive.
