"Unhandled ASN ..." by itself isn't fatal, but you might be running into another issue. Do your symptoms match those described here?

"Connection refused" means that upsd is not running, or not listening on the interface you expected. If you have a firewall set up, it is probably easier to use "LISTEN" to listen on all IPv4 addresses, rather than choosing a specific IP to listen on (as older versions of upsd.conf tend to recommend).
