Clip2, who supplied the addresses to Gnutella clients so they can connect to the Gnutella "network" is out of business. That is probably the cause of many of the problems listed above. I remember having to manually type in an IP address of a client already connected back in the day - this would be a workaround - but I can't find a list of addresses anywhere. The Hosts/Servers list on GnutellaNews doesn't seem to work either.
