Jenkins slave is not showing any log

Some time Jenkins Slaves are neither showing any log nor getting connected and you may feel that its stuck somewhere.

Problem – The main problem could be the last connection was not cleaned up properly and its hung that is why nothing is shown in UI log.

Solution – Try to disconnect and kill the process in slave if any and then try to reconnect again .
Another option is that try to reconfigure slave with wrong config (say wrong port) are relaunch again, It will fail and cleanup connection, again configure back and relaunch, this should work.
