It's your web browser which is looking at localhost.  That's right
because localhost is where Koha is running and it's Koha which is
trying to connect to z3950.loc.gov and reporting a connection failure.
Your web browser probably can't speak z39.50 protocol - HTTP is its

If you're at a school, I'd expect the firewall is forbidding UDP
connections on port 7090 and you need to talk to the network
administrator to let the Koha server through.

Hope that helps,
