It looks to me like the Squid in the states is not allowing access from
the German Squid (either by http_access rules on the US Squid or by fire
walling). Solving this problem would require knowing a bit more about
your network topology (is the US Squid accessible from the general
Internet, or do you have some kind of tunneling/VPN set up between the
offices?), and your US Squid http_access rules (are you allowing access
from the German Squid either by IP address or by password?).
