In Koha menu "Administration > Z39.50/SRU servers administration

you'll find the hostname/port for the Library of Congress are 
lx2.loc.gov:210 - thus you could test if this host is accessible from 
your own host:

$ telnet lx2.loc.gov 210
Trying 140.147.239.58...
Connected to lx2.loc.gov.
Escape character is '^]'.

$ nc -vz lx2.loc.gov 210
Connection to lx2.loc.gov (140.147.239.58) 210 port [tcp/z3950] succeeded!

If your output looks else you'll probably have to talk to your 
network/firewall administrator.

Hope this helps.

Best wishes: Michael
