Cannot connect to remote host

Hi,

I working with clion for 3 months and everything went pretty good until an hour ago when the IDE ask from me to restart clion due to some fail that related to saving or something, I'm not really remember. So i restarted clion and after that the deployment button under Tools just vanished for no reason. I checked also under Settings -> Build, Execution, Deployment and the deployment button also gone off. I restarted the computer and re-register to clion and nothing worked out. What do i need to do?

Thanks for the helpers.
