Connection refuse Error after 25-30 min

I am getting this message after 25- 30 min of labs, "The connection to the server 172.17.0.13:6443 was refused - did you specify the right host or port? "
I am doing the CKS mock exam 1. Please suggest if this is due to recent migration or some action is needed from user end.
Thanks.
