When you disable the firewall "just to test something real quick" and suddenly the server and client are holding hands like they're on a first date. No barriers, no protection, just raw TCP/IP connection flowing freely between them. Sure, your security team is having a meltdown somewhere, but at least you figured out why your app wasn't working. Spoiler: it was always the firewall. It's always the firewall. Now you just need to remember to turn it back on... eventually... maybe after lunch.
