sounds like you have auto-reconnect enabled and the connection is not establishing.

look at both keyclones, do they both show the connection line or just one?

if only one, then go to the keyclone that is trying to connect.. go to keyclone/setup/general ... and compare the ip and port with the ip and port on the other keyclone's titlebar (look carefully)

if that is a match, and assuming both machines are on the same subnet, then the issue is usually a newly installed software firewall that is blocking.

let me know if any of this helps,
