      My only Jenkins slave dies every day almost at the same time giving below error :

      AT the same time, Jenkins Server (master) exhibits following logs:

      I only understood that Client/Server both are not able to connect to each other due to some reason and failed. However, it works for rest of the day when it is started manually after above error. There is no firewall/selinux running on any of the server.
