Ah, great—you managed to navigate to it, even if AMP played “hide the Diagnostics”! Not sure why AMP decided to list it under some cryptic spot. Anyway, is that all it provided you, or is there a more detailed section related to the Minecraft server or any memory-related hints?
Check through for crash/termination logs, resource usage, or anything mentioning system memory or OOM. Post it here as plain text when you find it. We’re looking for any clue as to why your server keeps rebooting itself. If this doesn’t yield results, we’ll move on to reviewing the Minecraft server logs directly.
