OK, the error I now get is this (nginx error log file):

[quote]
[error] 27054#0: *233 no "ssl_certificate" is defined in server listening on SSL port while SSL handshaking, client: 77.97.200.235, server: 0.0.0.0:443
[/quote]

In the Firefox this appears as "The connection to the server was reset while the page was loading.".

This is when I set the default for port 443 to "*:443 default ssl".

If I just set the default to "*:443" I get the browser error "Error code: ssl_error_rx_record_too_long" (in various browsers).
