--aspect not --ar in V6+), verify your Fast Hours balance, and simplify complex prompts. Remove parameters one at a time until generation succeeds. Most errors resolve in under 5 minutes.
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
- Check Basic Syntax: Verify command starts with
/imagine prompt:, correct parameter format - Verify Subscription: Run
/info, check Fast Hours, ensure active subscription - Test Minimal Prompt: Start with "a cat", add parameters gradually
- Check Discord: Verify connection, check status.midjourney.com, try different channel
- 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.

Frequently Asked Questions
Why does Midjourney say "Invalid parameter" for my prompt?
Midjourney V6+ changed several parameter names. The most common: use --aspect instead of --ar, and --stylize instead of --s. Check the official Midjourney documentation for the current parameter list for your version.
What does "out of Fast Hours" mean in Midjourney?
Fast Hours are the monthly GPU compute allocation for your subscription. When exhausted, generations switch to Relax mode (slower queue, no extra charge on Standard/Pro plans) or stop entirely on Basic plans. Upgrade your plan or wait for monthly reset.
Why are my Midjourney images blurry or low quality?
Low quality usually results from using --quality 0.25 or --q 0.25 for speed. Set --quality 1 (the default) for full quality. Also, upscaling with the U1-U4 buttons after initial generation significantly improves sharpness.
How do I fix Midjourney when it just shows an error and no image?
First, try resubmitting the exact same prompt — errors are often temporary server issues. If it fails repeatedly, simplify your prompt, remove all custom parameters, and retest. Check Discord server status and the #status channel in the Midjourney Discord.
