using a tcp socket fail to connect

[alexwbaule]

Recently i update my unbound_exporter, and using in a opnsense on port 953, the connection can't be made, using tcp.

looking on the logs, i got.

time=2025-12-17T09:32:45.118-03:00 level=ERROR source=unbound_exporter.go:664 msg="Failed to scrape socket" err="dial tcp: missing address"

And looking on the code, i got that the "host" on UnboundExporter is using a wrong value (u.Path).

I Ifx it.
