Rails - Terminal won't connect with error "can't open socket"


Hi everyone,

I left my computer opened on Cloud9 for lunch and got this error when I came back. I restarted my app several times, tried to close / re-open the terminal and reset the workspace with ?reset=1 but I am still having this error.

ctrl+c or ctrl+d won’t do anything. Also I cannot type anything in the terminal tab:

Thanks for your help,

Try restarting the workspace


Before posting to the support blog, I restarted the workspace couple of time but still had the issue.

Weirdly enough it is now back to normal!

Thanks anyway :slight_smile: and happy Christmas.
