Including fallback to your laptop if nothing else works. I saved a demo once by just running the whole thing from my computer when the Kubernetes guys couldn't figure out why the deployed version was 403'ing. Just had to poke the touchpad every so often so it didn't go to sleep.

Unwarranted tip: next time, if you use macOS, just open the terminal and run `caffeinate -imdsu`.
I assume Linux/Windows have something similar built-in (and if not built-in, something that's easily available). For Windows, I know that PowerToys suite of nifty tools (officially provided by Microsoft) has Awake util, but that's just one of many similar options.
You can just turn of automatic sleep/screen off in Windows native power settings.
