Can you confirm that the webui works when all servers are DOWN?
It’s definitely not the directory names (based on your output pm), but it could be that MineOS.
If profiles/basic functionality work when the servers are down, it tells me that MineOS is failing because it’s trying to interact with a server heartbeat (‘ping’ in minecraft parlance), but it isn’t getting a format it recognizes.
In fact, it might turn out that it’s revolving around one particular kind of server type, and if that’s the case, let me know what the server type is so I can attempt to reproduce (to create a fix).
Also I ought to try out node v9.5 like you are, because MineOS-node was built off a different branch, 4.x (4x isn’t simply an older branch, it’s an independent branch).
