I've put together a server machine I keep at home and I've tried to put together a Minecraft server using the modpack 'Valhelsia 2' but have run into several issues.
These questions may be rather Minecraft related, but I'm seeking help here since the server runs perfectly well when run from a batch file outside of AMP. (AMP is running on a Windows Server 2016 machine)
Since Valhelsia 2 is a relatively new modpack on the Twitch launcher and isn't on the old FTB launcher, there is no specific preset config available for it when setting up an AMP instance (unless I'm missing it), so I've had to do some serious mental gymnastics trying to get it to work.
The primary issue is that the server simply will not stay up for much longer than 30 seconds. I have tried using the Official (Vanilla) option while setting the version to 1.15.2, I have tried using the 'Custom' option (while trying my hardest to input the correct custom arguments), and I have tried using the 'forge' option while setting the version to the version of forge Valhelsia 2 uses.
With all of these methods, I have pointed the instance to the forge Jar file in the server directory, but the server will either stop within 5 seconds and won't use any system resources, or it will begin to use system resources for less than a minute and will eventually crash when trying to load a certain mod, which is sometimes a different mod each time. (I experienced a near-identical issue to this when trying to run the server on Ubuntu Server)
The server currently has 6GB of RAM allocated.
Hope someone out there can help, would be disappointed to know I can't use AMP.
Thanks in advance, - Matt
