Multiplayer Error Codes
October 9, 2026 at 09:49 PM
Added the complete published multiplayer code and meaning list
Star Wars: Galactic Racer uses multiplayer status and error codes to describe connection, session and matchmaking results. The list below records the 62 published code-and-meaning pairs. It is explicitly not a definitive list, and some entries describe successful results rather than failures.
GR-01 is labeled Engine Networking Issues and GR-06 Matchmaking Issues. The other groups are kept under their code prefixes without inventing additional category names. GR-02-00 records a working join and GR-03-00 means Success; their presence does not itself indicate an error.

Restart the game or session first, and restart the PC, console or cloud session if the problem persists. On Steam, use Properties, Installed Files, Verify integrity of game files to check installation data. These are general support steps, not a promise that each listed code has the same cause or fix.
If an error is not listed or continues after the general checks, submit a customer-support request with the displayed code and the requested problem details. The dated launch defects, including party reconnection problems, are recorded on Known Issues and Troubleshooting. Party size, race capacity and matchmaking behavior belong on Multiplayer.
