Hi. I have unreliable power at my house and when the power goes out, the server comes back up before the internet does. In that scenario, my Minecraft server doesn't start up. When it can't reach the download servers for the latest version, it tries to fallback to a specific old version of Minecraft and when it can't download that either, it gives up on starting altogether.
In that case I think it should start with whichever version is currently installed. Here are the logs from the startup:
---Starting...---
---Trying to get latest version from Minecraft Bedrock Edition from alternative source---
---Can't get latest version from Minecraft Bedrock falling back to v 1.16.20.03---
---Version missmatch Installed: v1.19.11.01 - Prefered:1.16.20.03, downloading v1.16.20.03---
---Something went wrong, can't download Minecraft Bedrock Edition, putting server in sleep mode---
