Firewall domain names whitelist

Works with
Section

In some cases, the computers using MCreator are behind a firewall or proxy. A common case of this is classrooms in schools, summer camps, and STEM workshops.

Domain list

In order to be able to use MCreator under a restrictive firewall, at least the following domains need to be whitelisted:

  • jcenter.bintray.com
  • files.minecraftforge.net
  • github.com
  • modcoderpack.com
  • repo.maven.apache.org
  • libraries.minecraft.net
  • launcher.mojang.com
  • mcreator.net

If protocol selection is required, allow both HTTP and HTTPS connections.

Offline mode

If the classroom does not have an internet connection, you can use the offline mode of MCreator that can be enabled in preferences. Keep in mind that the initial setup and first workspace creation for a given Minecraft version still require internet connection.

Whenever possible, avoid using offline mode as it can cause many unpredictable errors and cache corruption which requires intervention described on this page: https://mcreator.net/wiki/gradle-setup-errors.



Donate to MCreator

By donating to developers you can speed up development, as with more resources, we can dedicate more time to MCreator. It is a free project made by developers working on it in their free time.
