From the Fog Reimagined Server & Aternos Notes

Choose matching server files

The creator provides a dedicated server pack. For the checked 6.3.2 release, use client file 9191040 with server file 9191062. Both are listed for Minecraft 1.20.1 and Forge.

Before starting a server

1. Agree on a release

   Have every player check their modpack version. Match the server release to it; matching Minecraft 1.20.1 alone is not enough to identify the pack release.

2. Use the server package

   Download the matching server pack from the author’s file page. Follow the included instructions and your host’s supported installation procedure. This file-selection guide does not prescribe an unverified startup command.

3. Check host support before paying

   Ask whether the exact Reimagined release is available or whether the host supports its server pack. Confirm its resource limits and backup process. A similarly named base mod or plugin is not the same package.

4. Keep useful error details

   If joining fails, record both pack versions and the error message. See the troubleshooting guide before changing the mod set. Remove tokens, addresses or other private details before sharing logs publicly.

Can I use Aternos?

Aternos appears in Google suggestions for this pack, but a suggestion is not a compatibility confirmation. This guide has not verified a current Aternos listing for Reimagined 6.3.2. Check the exact pack name, creator and version in the host’s modpack selection before committing to that route.

If the exact pack is absent, installing the base From The Fog mod or a similarly named plugin is not an equivalent setup. Use the official server package with a host that explicitly supports it.

How much server memory?

The creator’s notes say a minimum of 6 GB but also contain a conflicting parenthetical figure of 5 GB for ten players. We therefore do not provide a player-count formula. Confirm resource requirements with the current server instructions and host for your chosen release.

What about an incompatible mod list warning?

The author’s current notes say to try joining even if the server displays an incompatible mod list or FML version warning. First verify that the client and server are a matching release. This advice does not mean arbitrary versions work together; use the creator’s support channel if the connection fails.
