|---|---|---|
| GPT-5.6 Error | Startup, service or connection path | Check OpenAI status |
| Only your device is affected | Local files, app, security or network | Continue through the fixes below |
| Many users are affected | Service-side outage or capacity | Check official status before reinstalling |

Fastest Troubleshooting Order
| Priority | Action | Why |
|---|---|---|
| 1 | Check OpenAI status | Quick, low-risk test |

| 3 | Retry a shorter version of the prompt | Checks local files or components |

How to Tell If It Is a Server-Side Problem
A single error message does not prove that the service is down. Look for a pattern. If the issue begins at the same time for many users, the official status page or community reports show a spike, and the problem survives across devices or networks, the service side becomes more likely.
If other users can connect normally but your device still fails, focus on the local app, game files, browser, security software or network path. This distinction matters because reinstalling software cannot repair an upstream outage.
What Not to Do
- Do not repeatedly reinstall while a service outage is still active.
- Do not download unofficial “error fixer” executables.
- Do not permanently disable antivirus or firewall protection.
- Do not delete saves, account data or configuration folders unless an official guide specifically requires it.
- Do not change several settings at once; one change at a time makes the real cause easier to identify.
