Video stuck in queue
Standard 5s: 2–5 min. Pro 10s: up to 15 min. During peak: add 2–5 min. Refresh page and check Generations tab. Cancel and resubmit after 20 minutes if still stuck.
Generation failed / content policy
Kling blocks political content, real person likenesses, explicit violence. Remove person names, political descriptors. Focus on scene + motion: "a figure walks through autumn leaves" not a named person.
Credits exhausted
Free: 66 credits/mo. Standard 5s = 10 credits. Pro 5s = 35 credits. Pro 10s = 70 credits. Check balance at klingai.com → account. Monthly reset on billing cycle date.
API JWT auth error
JWT requires HS256 signature. Secret Key must be base64-decoded before use as HMAC secret. Payload needs iss, exp (30min+), nbf. Regenerate keys at klingai.com → API if 401 persists.
Poor motion quality
Use Kling 1.6 Pro for best human motion. Describe motion explicitly: "person walks forward slowly, arms swinging naturally". Image-to-video: use high-resolution starting image (1080p+) with clear subject.
Login / account access issues
Kling is operated by Kuaishou (China). Login uses Google OAuth or email. If Google OAuth fails, try email login. Some regions may have restricted access — use email registration as fallback.
Kling credit costs per generation
| Model | Duration | Credits | Quality |

| Kling 1.6 Pro (1080p) | 10 seconds | 100 credits | Highest |
Free plan: 66 credits/month. Subscription plans start at ~$9.99/mo for more credits.
Kling API JWT authentication guide
Python JWT example
import jwt
import time
import base64
access_key_id = "your_access_key_id"
secret_key = "your_secret_key"
payload = {
"iss": access_key_id,
"exp": int(time.time()) + 1800, # 30 minutes
"nbf": int(time.time()) - 5
}
# Note: secret_key is used directly (NOT base64-decoded) in most SDK versions
token = jwt.encode(payload, secret_key, algorithm="HS256")
# Use in header: Authorization: Bearer {token} API base URL: https://api.klingai.com. Generate videos: POST /v1/videos/text2video. Poll status: GET /v1/videos/text2video/{task_id}.
Step-by-step fix
- 1
Check live Kling AI status
Visit prismix.dev/service/kling. Kling is operated from China by Kuaishou, so peak times and status update patterns differ from US-based services. Slow generation during your morning hours may be peak time in Asia.
- 2
Fix stuck video generation
Refresh klingai.com — video may have completed. Check Generations tab. Cancel and resubmit if stuck beyond 20 minutes. For Pro 10s generations, 15 minutes is normal during peak demand — wait before cancelling.
- 3
Fix content policy failures
Kling blocks: political figures + political content, specific real person likenesses, explicit violence, adult content. Replace with scene-first descriptions: "a young person in a city street at golden hour" instead of a named individual. Focus on motion, lighting, and environment.
- 4
Fix API JWT authentication
JWT errors are the most common Kling API issue. Confirm: (1) algorithm is HS256; (2) payload includes iss=your Access Key ID, exp=future Unix timestamp, nbf=current Unix timestamp; (3) exp must be at least 30 seconds from now. Regenerate API keys at klingai.com → account → API Keys if 401 persists after fixing JWT.
- 5
Improve video motion quality
For better Kling results: use Kling 1.6 Pro model (not Standard) for human motion. Add explicit motion descriptions: "slow pan from left to right", "character turns head and smiles". For image-to-video: use a high-resolution starting image (1080p minimum). Add negative prompts: "blurry, distorted, jerky motion".

Frequently asked questions
Why is Kling AI not working?
Kling AI not working is usually: slow queue (operated from China, peak times differ), content policy block (remove political/real person content), credits exhausted (check klingai.com account), API JWT auth error (HS256, iss/exp/nbf payload), or platform outage (check prismix.dev/service/kling).
Is Kling AI down right now?
Check prismix.dev/service/kling for live status. Because Kling is operated by Kuaishou from China, peak load and downtime patterns differ from US/EU AI services.
How long does Kling video generation take?
Standard 5s: 2–5 minutes. Standard 10s: 4–8 minutes. Pro 5s: 5–10 minutes. Pro 10s: 8–15 minutes. Add 2–5 minutes during peak demand. Refresh the page after expected time — videos often complete silently.
How to fix Kling API JWT 401 error?
JWT 401 error: (1) algorithm must be HS256; (2) payload must include iss=Access Key ID, exp=Unix timestamp 30+ minutes ahead, nbf=current Unix timestamp; (3) sign with Secret Key directly (check if your SDK version needs base64-decode or not). Tokens expire after 30 minutes — generate a fresh token per request batch.
Kling AI vs Luma Dream Machine — which is better?
Kling 1.6 Pro produces better realistic human motion (walking, gestures, facial expressions). Luma Dream Machine has a faster interface and better US-region queue times. Kling is operated from China so support and timezone differ. For character motion video, Kling Pro leads. For abstract and landscape video, both are comparable.
