I am getting this error when i run the command: cap rubber:create_staging

I just found a workaround, although I'm not sure how secure it is.

I went onto my instance and edited the default group. I removed all the inbound rules except for the most basic one. This one I then opened up to anyone:

That seemed to fix the problem.
