SSL: logging level of "peer closed connection in SSL handshake". Previously, the NGX_LOG_INFO level was used unconditionally. This is correct for client SSL connections, but too low for connections to upstream servers. To resolve this, ngx_connection_error() now used to log this error, it will select logging level appropriately. With this change, if an upstream connection is closed during SSL handshake, it is now properly logged at "error" level.
