Well it is ssh that is failing so you need to check why ssh to the host is no longer working. Note one trick is to use one ssh connection but multiple sessions which should speed up things. See https://tutonics.com/articles/allow-multiple-ssh-sessions-over-an-existing-connection/ for more info on that.
