when you exit a router from the console or "octal line", you are running a chance to get this connection refused by remote host
when you exit a router, hit cntrl shift 6
then type 'disconnect'
enter to confirm
then clear line (line #)
if you disconnect from it properly, you won't have this problem
if clear line (line#) doesn't work once, use the up arrow and run it 3 to five times, it'll open..
