Hello community of HolyHosting! ๐ŸŒŸ

Today we're going to solve an error that many have encountered: "Unable to access jarfile /jar/minecraft_server.jar". This problem occurs when the server can't locate the designated .JAR file. But don't worry, here's a step-by-step guide so you can solve it easily. ๐Ÿš€

This error usually appears if:

  • The file .JARโ˜• has an incorrect name.
  • The file has been deleted or moved.

  • Stop the server from the Server Panel.

panel holyhostinga

  • Go to the "Files" section and confirm the name of the JAR file.

panel archivos

  • Rename the .jar file so it matches the name you verified earlier.

panel archivos

server.jar

  • Save the changes and restart the server.

Solution: Make sure you are in the correct folder and that the JAR file actually exists. If not, upload the file again.

If the above didn't work:

  • Stop the server from the Server Panel.
  • Select "Reset Server Files".

panel holyhosting

This will re-download the necessary base files, including the JAR file and any mods for the required version.

With these steps, you should be able to fix the "Unable to access jarfile" error and get back to enjoying your server without issues. ๐ŸŽฎ We hope this guide has been useful and remember, don't hesitate to ask on HolyHosting Discordย or contact our support team.
