Nothing is more infuriating than being slapped with a “Kling AI failed to submit task, please try later” error. It can be totally surprising and confusing to deal with, particularly because you often have no clue what caused this issue in the first place or even how to fix it!

But don’t fret. Even if you are new to Kling AI, I’m here to provide a quick rundown of potential solutions that will get you back to generating videos in no time!

What Causes This Kling AI Error & How to Fix It?
Fixing this issue is possible. But it can be caused by any number of things, so you need to narrow it down. Sit back and let me list the potential reasons behind it and their solutions:
Temporary System Glitch
Sometimes, the problem could have simply been caused by a temporary glitch. To eliminate this as the cause, I suggest restarting the entire generation process by refreshing the page.
This will erase any configurations and prompts you set, so always note them down beforehand. Also, make sure your uploaded files meet the required specs in format, size, dimension, etc.
Server Downtimes
During peak business hours, Kling AI’s servers may be overloaded with requests, which can often cause this particular error to pop up. This is also especially common on the free tier.
To solve this, try again during off-peak hours, such as the morning, late at night, or on weekends. If you’re using the free tier, consider upgrading to a paid plan.
Browser Cache Issues
This is a common problem that frequently affects online users. Sometimes your browser cache can get corrupted, which prevents it from loading pages and processing tasks properly.
To fix this, just head over to your browser history and clear the cache data. Then close and restart the app before logging back into Kling AI to retry the video generation.
User Account Issues
In some cases, a task submission can be interrupted by a security issue like multiple failed login attempts or a detected password leak. Change your password, then try to regenerate.
Other times, it could be due to a policy violation, which can lead to a temporary account restriction. To verify this isn’t the problem, wait and try again later or send an email to support.
Account Payment Restrictions
Kling AI may have had issues processing your account payment. This could be due to an expired card, insufficient funds in your bank, or you’ve simply run out of credits.
Such issues can often cause blocked task submissions. So, just double-check that your credit limits, payment details, and account information are all in order.
Unstable Internet Connection
If your internet connection happens to cut out or drop while the generation process is starting, then this can cause a failed error. Check your router and restart it to help alleviate the issue.
You can also consider resetting your computer’s WiFi. And if you can, try switching to a mobile data or wired connection, then try generating the video again for good measure.
Problem Still Unknown: Contact the Support Team
If you’ve explored all these potential causes and are still faced with the ‘Failed to submit task’ error, then go ahead and contact Kling AI support for help.
You can email them or reach out via social media, but always be direct and specific in your communication to get a swift response.
