Thanks!

Hi, this fix seems to be mostly working, not always working for me. 5 tries with 5 seconds delay (~25 seconds total) is not adequate it seems all the time. Maybe AWS is getting slower at creating and configuring security groups. Can this be extended to allow for more time? or maybe change to a configuration parameter. I suspect no harm in looping 10 times?? Total ~50 seconds.

I'd suggest opening a new issue - reference this issue and submit a pull request to adjust the parameters.

Just happened to me twice. 3rd time worked.
