When restricted via firewall app just hangs

[cxhercules]

When behind firewall and app does not have access to download script here ti just hangs:

curl -s https://raw.githubusercontent.com/danhigham/cf-console/master/install.sh > /tmp/install.sh && bash /tmp/install.sh && sleep 3600

Another surprise was that even though I uninstalled on app that I tested this with it stayed around in app parameters. So when a deploy was done it started failing, and did not know why. When looking at logs would just repeat below sequence.

Not till I tried starting app with CF_TRACE=true did I see the above command was embedded in app:
