I want to install forge version 1.11.2.
When I run the server (accept EULA and start), the server starts and crashes 20s later.
In addition I have no logs or console that opens!
I specify that I have tried with the vanilla versions and everything works.
Are there any errors in the mineos.log file when it crashes?
Which MineOS distro are you using? If you are using Jessie, or other older version, then I suggest upgrading. You might be running on an outdated nodejs.
