Problem Description

Issue

I have tried to port my old server to the software, the first part went well as i was able to create the instance and run it via my domain. But after trying to move my world and mods to the server, it no longer started. I tried a few things to hopefully get it working again, but nothing worked. I did figure out that simply starting the run.bat file, the server does start, which makes it seem that the server is fine and should just work

Reproduction Steps

  • Created a new instance
  • Set up the instance to forge and the correct forge version
  • Ran the server to create all files and then accepted the EULA
  • replaced the mods and world folder with the data of my old server
  • Started the server again
  • Server does not start, saying it is caused by something outside of AMP

As the error says, you’ll need to read the log to see why it won’t start.

Common problems would be using the wrong Java runtime for the Forge version you’re running, or not dedicating enough memory to the instance. (Java 8 for anything 1.16 and older, Java 17 for anything 1.17-1.20.4, then Java 21 for anything newer)

I’ve checked the logs but there is no clear error that says why it couldnt start. There is also no difference between starting it from the panel and starting from the exe file, the logs seem exactly the same. but when using the panel it just won’t start. i’ve checked the forge and java versions, and they’re both correct so i still have no clue what is stopping it from starting

Verify that enough memory (RAM) is allocated. This can be configured in the server settings of the panel.

Carefully review the server logs. Even if there are no clear error messages, there might be warnings or hints about issues with plugins or mods.

Check the AMP (Application Management Panel) settings. There might be specific configurations or restrictions preventing the server from starting.

Review the server.properties file and other configuration files for any errors or inappropriate settings.

If all else fails, create a completely new instance and migrate the data step-by-step to identify the exact point of failure.

Thank you both for the answers, this got me looking in the right locations.

I found the issue and fixed it. After reading a couple of other posts I found out that AMP had no write access to the world folder because I put it there via file explorer. So I removed the folder and re uploaded it via the SFTP. After that It started right up!

Initially I wanted to do it via SFTP but it was INSANELY slow, so I thought this was a better idea but apparently not. So now after waiting 2 hours for it to upload it works!

I use this one to down and upload: WinSCP :: Official Site :: Download

When your connection to your server is fast then I think this is the way to go.
