[Unraid] Multiple exceptions preventing server staying up

Java
1

I’m currently in the process of shifting my Minecraft server from a more basic docker to MineOS. Allocating ports, accessing the web UI, importing the world file, and everything up to launching the server has gone swimmingly. However, every time I attempt to launch the server, it stops after about ten seconds. The logs say this:

14:37:58] [main/INFO]: Environment: authHost=‘https://authserver.mojang.com’, accountsHost=‘https://api.mojang.com’, sessionHost=‘https://sessionserver.mojang.com’, servicesHost=‘https://api.minecraftservices.com’, name=‘PROD’

It seems to me (based on my cursory knowledge) that the actual jar of 1.16.5 is causing the issue, but since I downloaded the official Mojang jar directly from the Profiles tab of the web UI, I doubt that’s it. Any thoughts on what could be causing the issue?

This looks like a filesystem rights issue.

So is it a problem with the cache permissions where the Minecraft files are stored?

Most likely it is is a user:group ownership problem on the seerver directory and files .

Or maybe a file attribute problem on the JAR file (not set runnable). ?

I managed to get it working. It was a simple matter of updating Unraid.
