Issues with creating certain Jar versions

I’ve been running MineOS for about four days now and I’ve been having trouble installing older versions of both Paper and CraftBukkit. I can install Paper version 1.8 fine, except 1.8 is no good for me as Essentials isn’t supported. I’ve been trying to install 1.8.8 but every time I start the server with said version, I try to connect to it on the hub (I’m running a network) and get the error:

Exception Connecting:NativeIoException : readAddress(…) failed: Connection reset by peer.

I’ve tried installing 1.8.5, 1.9.4, 1.11.2 and I always get the same message. The only versions I can comfortably install without any of this are 1.8 and 1.16.5. When I get this error I try to shut down the Factions instance but the panel stops responding. I refresh the WebUI and it fails to load and the machine I’m running MineOS on shuts down shortly after. I’d supply you with logs, but when I go to the panel I get the whole “Log tailing has stopped” message, and I can’t refresh to load those logs because the panel simply won’t load.

Any help? Thanks!

Edit: I should probably tell you some specs. I dont think any of this matters as it’s definitely not a HDD issue or ram issue, as I can comfortably run about 5 instances, but trying to run 1 1.8.8 instance crashes the machine

HDD: 256gb
Ram: 32gb DDR3
CPU: AMD FX 8300 6 core
