Midjourney Prompt Not Accepted | Fix

Facing the “Midjourney Prompt Not Accepted” issue? This clear guide explains causes, solutions, and expert fixes in simple steps.

What Is the Midjourney Prompt Not Accepted Issue?

If you’ve been using Midjourney to generate images, you may have encountered a confusing message: “Prompt Not Accepted.” It might appear unexpectedly, even when your input seems perfectly fine. This message can stop your creative process, making it frustrating to understand what went wrong or how to move forward. Fortunately, it’s not as mysterious as it feels — and solving it is often easier than expected.

This issue usually happens when the prompt you enter doesn’t meet Midjourney’s input standards. These standards aren’t always clearly explained, which is why users sometimes feel stuck. Whether it’s due to banned words, incorrect formatting, or prompt length, knowing the exact cause makes all the difference.

Here’s why this matters:

• 🧩 Creative Block: Not knowing why a prompt fails can interrupt your design flow and slow down productivity.
• ⚙️ Technical Confusion: New users might think it’s a bug, when it’s usually a simple formatting or rules issue.
• 🚫 Unclear Restrictions: Midjourney has internal filters for content that may not always be obvious to users.
• 🖼️ Output Delay: Every failed prompt delays your final image, wasting valuable time during project work.
• 📋 User Experience: Repeated failures can be discouraging for both beginners and experienced users.

Let’s break it down step by step and solve this together.

🔍 Most Common Causes of Midjourney Prompt Not Accepted

Before we dive into solutions, let’s look at why this happens in the first place. Most problems are related to how the prompt is written or what it contains.

🛠️ How to Fix Midjourney Prompt Not Accepted

Let’s fix this together. Even if you’re unsure what went wrong, these steps can help you get back on track and ensure your prompts are accepted by Midjourney.

1. 🧹 Remove Banned Words

🧠 Why it works:
Midjourney automatically blocks prompts containing words on its restricted list, even if they seem harmless.

📌 How to do it:
• Cross-check your prompt against a Midjourney banned words list
• Replace sensitive words with more neutral alternatives
• Avoid political, adult, or violent terms entirely

2. ✂️ Shorten Long Prompts

🧠 Why it works:
Excessively long prompts may exceed token limits or become too difficult for the parser to interpret.

📌 How to do it:
• Limit prompt length to under 60 words
• Focus on the subject and 3–5 key descriptive terms
• Remove duplicate or unnecessary modifiers

3. 📐 Follow Prompt Structure Guidelines

🧠 Why it works:
Following basic Midjourney prompt structure rules improves readability and acceptance.

📌 How to do it:
• Start with the subject (e.g., “a forest scene”)
• Add adjectives or mood (e.g., “misty, calm”)
• End with style or camera terms (e.g., “cinematic lighting, DSLR look”)

4. 🔄 Rephrase Conflicting Details

🧠 Why it works:
Prompts with contradicting elements confuse the model and are often rejected.

📌 How to do it:
• Avoid using terms like “dark sunlight” or “empty crowded”
• Choose a clear, single direction for style or time of day
• Simplify where needed

5. 🔤 Avoid Unsupported Characters

🧠 Why it works:
Some characters (like emojis or certain non-Latin fonts) are not processed properly.

📌 How to do it:
• Use standard ASCII characters only
• Remove emojis, special dashes, or language-specific characters
• Stick with simple punctuation

6. 🧮 Use Correct Weighting Format

🧠 Why it works:
Incorrect prompt weighting syntax leads to prompt rejection.

📌 How to do it:
• Use double colons like cat::2
• Avoid using triple colons or symbols Midjourney does not recognize
• Keep weighting logic consistent and minimal

7. 🧭 Split Complex Prompts

🧠 Why it works:
Breaking up complicated prompts makes it easier to test and locate the error.

📌 How to do it:
• Copy your prompt into two parts and test each separately
• Combine again once you’ve isolated the issue
• Try simplifying visual themes

8. 🧾 Validate Prompt in Discord

🧠 Why it works:
Discord often provides error feedback not visible in the web interface.

📌 How to do it:
• Paste the prompt directly into the Midjourney bot in Discord
• Review any error message provided
• Adjust based on that feedback

9. 📚 Read Midjourney Prompt Rules

🧠 Why it works:
Knowing the latest updates helps avoid prompt rejections due to recent rule changes.

📌 How to do it:
• Visit Midjourney’s official documentation
• Search for “prompt guidelines” or “restricted words”
• Stay updated as policies change often

10. 🧠 Rebuild Prompt from Scratch

🧠 Why it works:
Sometimes it’s easier to start fresh than fix a tangled prompt.

📌 How to do it:
• Write a short version of your idea first
• Add only key descriptive terms
• Build up gradually, testing each addition

🧪 Advanced Troubleshooting Tips

If none of the basic solutions worked, here are some advanced steps that can resolve persistent Midjourney Prompt Not Accepted issues:

1. 🌐 Check Proxy or VPN Settings

🧠 Why it works:
Some connection issues due to VPNs can affect how prompts are processed, especially in restricted regions.

📌 How to do it:
• Disable VPN or switch server
• Check Midjourney’s accessibility in your region
• Try using a different internet provider if blocked

2. 🔎 Analyze Prompt Rejection with DevTools

🧠 Why it works:
Browser developer tools can reveal if a prompt is being blocked at submission level.

📌 How to do it:
• Open browser console (F12 or right-click → Inspect → Console)
• Submit your prompt and watch for error messages
• Identify blocked content or failed API call

3. 🧭 Inspect API Logs

🧠 Why it works:
If you’re using Midjourney through an integration, logs may show why a prompt failed.

📌 How to do it:
• Access your integration’s error logs
• Check for 400 or 403 errors
• Match them to specific prompt patterns

4. ⏰ Sync System Time

🧠 Why it works:
Out-of-sync system clocks can cause certificate or connection errors when submitting prompts.

📌 How to do it:
• Check your device’s system time and timezone
• Enable auto-sync with internet time
• Restart Midjourney bot connection if needed
