Check a GrimAC issue against the actual client and protocol path

Applies to: GrimAC; match the linked maintainer documentation to your installed platform and release.
Documentation checked 9 November 2026.

A movement problem limited to one client version may depend on protocol translation rather than the player’s connection alone. Record the full path before changing anticheat thresholds.

Follow the procedure

Collect the affected client version and edition, backend Minecraft version, proxy software and any protocol translation plugins. Record where each component runs.
Compare this combination with Grim’s current supported-platform and compatibility guidance. A plugin enabling successfully is not a guarantee that every translated client path is supported.
Ask the affected player to describe the exact ordinary action and location. Note whether the result is an alert, setback, disconnection or another plugin’s punishment.
Repeat that action with an unmodified test client matching the affected version. Compare a directly supported client version through the same public route without opening protected backend ports.
Collect the matching Grim profile or prediction diagnostic and relevant server timing evidence. Change one compatibility variable at a time in staging, not several production plugins together.
Use an official compatible update or documented mitigation when the evidence identifies a known integration issue. Keep the previous matched plugin set available for rollback.

Check the result

The comparison should establish whether the symptom follows the client/protocol combination, a location or general server load. Record a result for both test clients. Different symptoms should remain separate rather than being grouped under a generic false-positive label.

If the result is wrong

If compatibility remains uncertain, send the maintainer the exact version matrix and narrow diagnostic log. Do not promise support from a different release’s documentation. Restore any unsuccessful trial update with its matching configuration, and avoid weakening all movement checks for an unconfirmed cause.
