Kling AI is Kuaishou’s generative video and image platform, one of the most widely used AI video generators in the world. People rely on it for text-to-video, image-to-video, Kolors image generation, lip sync, motion control, and virtual try-on clips, through the web app at kling.ai, the mobile apps, and a developer API. Because renders take time and cost credits, an outage or a jammed queue hurts more here than in most AI tools. Start with the live verdict and user reports at the top of this page to see whether the problem is widespread or just your setup.
Common reasons Kling AI stops working
- Saturated GPU queue. Renders share GPU capacity, and when it fills at peak hours new jobs are rejected with “Failed to Submit Task, Please Try Later”.
- Final encoding stalls. Generations that freeze at 99% are hanging in the last encoding step, most often image-to-video jobs with no end frame, long durations, or extreme aspect ratios.
- Multi-hour queue delays. During high-traffic periods, generations can queue for two to twenty-four hours even though the site loads fine.
- Login and verification failures. A looping “please complete security verification” CAPTCHA can block sign-in entirely, and account creation sometimes fails too.
- Region restrictions. Kling AI is not available in every country, and “Access Denied” errors typically appear after VPN or IP changes or from unsupported regions.
- Credit and moderation problems. Credits are consumed on failed or moderation-rejected generations, which can look like a billing fault when jobs keep dying under load.
How to fix Kling AI when it is not working
- Check the status at the top of this page first. If our check and user reports show a broad problem, waiting is the fastest fix, and retrying into a saturated queue just burns credits.
- Give a stuck render time before cancelling. Jobs frozen at 99% often complete after a long final encoding step, and cancelling then resubmitting spends more credits.
- Retry with simpler settings. If image-to-video keeps hanging, add an end frame, shorten the duration, or use a standard aspect ratio, since extreme jobs stall most.
- Wait out “Failed to Submit Task” errors. This rejection means the shared GPU queue is full. Resubmit after a few minutes, or generate at off-peak hours.
- Fix login loops in a clean browser. If security verification keeps repeating, clear your cache or open a private window, then complete the CAPTCHA once.
- Turn off your VPN. “Access Denied” errors are usually regional IP restrictions, and VPN or IP address changes commonly trigger them.
- Switch between the web app and the mobile app. The two can fail independently, so the other surface may still generate normally.

Is Kling AI down, or is it just you?
Compare your experience with what others are reporting. If the verdict and reports at the top of this page show a spike, the problem is shared and the fix is on Kuaishou’s side. Kling AI is unusual because the site can be reachable while the render queue is jammed, so “the page loads but my video never finishes” is still a service problem if many people report it at once. If reports are quiet, the cause is more likely local: your account, a VPN or regional restriction, or a job that exceeds current limits.
How we check Kling AI
Kling AI does not publish a public status page or a machine-readable status feed, so there is no official source to read. Instead, we run our own independent reachability check against Kling AI from the outside, on a regular interval, to confirm whether its endpoint is responding for us. We combine that signal with the crowd-sourced reports submitted by readers on this page, so the verdict reflects both an external probe and real user experience. A reachable website does not always mean the render queue is healthy, which is why reader reports matter here. You can read more about our approach on our methodology page.
Alternatives to Kling AI during an outage
If Kling AI is jammed or down, a few comparable generators can stand in. Runway and Luma both cover text-to-video and image-to-video work well, and MiniMax‘s Hailuo generator is a capable third option. (OpenAI’s Sora app was discontinued in March 2026, so it is no longer a fallback.) Check your backup’s live status before switching, since video platforms often strain at the same peak times. Keeping one alternative account ready means a multi-hour Kling AI queue does not stall your project.
Stuck at 99%: how Kling AI fails when demand spikes
Kling AI’s most recognizable failure is the render that freezes at exactly 99%. The generation runs normally, then hangs at the final encoding step, most often on image-to-video jobs with no end frame, long durations, or extreme aspect ratios. The same capacity crunch shows up as “Failed to Submit Task” rejections the instant you press Generate, and as queues stretching for hours on free and Standard tiers, all while kling.ai loads normally.
Access problems follow their own pattern. The international service at kling.ai runs separately from Kuaishou’s China domestic version, the global developer API is served from Singapore, and the web app, mobile apps, and API can fail independently. Kling AI is not available in every country, VPN and IP changes commonly trigger “Access Denied” blocks, and a looping security verification CAPTCHA can shut users out of login entirely, all of which look like downtime but are access limits.
- Progress bar frozen at exactly 99% with the video never delivered
- “Failed to Submit Task” the moment you press Generate
- Generations queued for hours while the site stays up
- Sudden “Access Denied” or a looping security verification at login
