Recently I came across some problems when using Juno:

```julia
Julia has exited.
Press Enter to start a new session.
Starting Julia...

It seems that Julia can’t connect to Atom, but REPL still displayed, I can still type and eval codes in REPL. But `Ctrl+C` and `Ctrl+D` won’t work, and I can’t use `Ctrl+enter` to eval codes in files.

```julia

OK,I have solved this problem by disabled firewall…It seems that Atom get blocked behind the firewall…
