I think you mean explicitly open the port on your router, but even then that’s not true. Plex by default will proxy your traffic so that even closed off servers can be reached. It is pretty easy to disable remote access in the server settings though.

I didn’t realize it would be so easy when I wrote the script. Knowing what I know now I’d just check adafruit every couple minutes starting a bit before 8:30am PST.

It’s not that difficult to get a Pi 4. I wrote a python script that scraped rpilocator’s rss feed every 5 minutes and would notify my phone when one was available in the US. It went off basically every day around 8:30am PST when Adafruit would drop 100+ Pi4s. I’ve picked up two in the past week (one for my Voron printer and another for a RetroPi cabinet). They did sell out fairly fast… in about 10 minutes or so.
