How to Fix Midjourney Image Generation Errors - Complete 2026 Guide

Direct Answer: The most common fix for Midjourney image generation errors is to check your prompt syntax, verify your subscription status, and ensure you're using supported parameters. Most errors can be resolved by removing unsupported parameters like --ar 16:9 (use --aspect 16:9 instead), checking your Fast Hours balance, or simplifying overly complex prompts.

Common Midjourney Errors & Quick Fixes

1. "Invalid Parameter" Error

Fix: Check parameter spelling. In Midjourney V6+, --ar changed to --aspect. Also verify version compatibility and remove conflicting parameters.

2. "Job Failed" or "Generation Failed"

Fix: Simplify your prompt, reduce image dimensions, check character count (under 1,000), or try a different seed. Server issues often resolve in 5-10 minutes.

3. "Out of Fast Hours" Error

Fix: Switch to Relax mode using /relax command, purchase more Fast Hours, or optimize usage by using Relax for experiments and Fast for final images.

4. "Banned Prompt" or "Content Warning"

Fix: Rephrase sensitive terms, remove trademarked names, avoid policy violations, or use --no parameter to exclude problematic content.

5. "Rate Limited" or "Too Many Requests"

Fix: Slow down (wait 10-30 seconds between generations), use Relax mode (no rate limits), or check queue position with /info command.

Step-by-Step Troubleshooting

1. Check Basic Syntax: Verify command starts with /imagine prompt:, correct parameter format
2. Verify Subscription: Run /info, check Fast Hours, ensure active subscription
3. Test Minimal Prompt: Start with "a cat", add parameters gradually
4. Check Discord: Verify connection, check status.midjourney.com, try different channel
5. Review Error Details: Read full message, note error codes, search docs

Parameter Compatibility

Key changes in V6+: --ar → --aspect. Always check official docs for latest parameter support as Midjourney updates frequently.
