Hi support_support817,

Thanks for reaching out to Jotform Support. Our Japanese Support agents are busy helping other Jotform users right now, so I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Japanese, let us know and we can have them do that. But, it might take a while until they're available again.

Now, coming back to your question, based on the error shown, it appears that your form users are being blocked by Cloudflare’s security system when attempting to submit the form. This typically happens when Cloudflare detects potentially harmful activity, such as malformed data, the use of special characters, or behavior resembling spam or bots, even if the user is legitimate.

Since you mentioned receiving at least four reports of this issue in a single day, we recommend a few countermeasures. First, if most of your users come from a known region, such as Japan, you can request that our backend team review the Cloudflare security rules to reduce sensitivity for those IPs or regions.

Next, review your form fields, especially long text or input fields, to ensure they don’t unintentionally allow characters or patterns that might trigger Cloudflare, such as special symbols, links, or embedded code. You can use input masks or character limits to help manage this. Adding CAPTCHA or reCAPTCHA to your form may also reduce the chance of submissions being flagged as suspicious.

Keep us updated and let us know if you need any more help.

ご返信ありがとうございます。

では、Cloudflareのセキュリティルールの感度を、特定の地域「日本」に対して、下げてください。
お手数ですが、バックエンドチームへの依頼をお願いします。

Hi support_support817,

Our Developers are on the case and doing their best to get this sorted quickly. We’ll update you as soon as we can.

Hi support_support817,

Based on my check, it appears that the access issue has been resolved.

Could you check and confirm that if you are currently experiencing any access issues from Japan?

ご対応いただき、ありがとうございます。

Hi support_support817,

We'll need to investigate further on this last issue to understand if it could be related to the initial issue related to Cloudfare. To do that, we’ll need your permission to access your account. Don’t worry, you can turn it off again once we’re done. Let me show you how to do it:

1. In the top-right corner of your Workspace page, click on your Avatar/Profile Image icon.

2. In the Dropdown menu that opens, click on Settings.

3. Next, in the panel on the left, click on the Security tab.

4. If you haven’t opened your Security page in a while, it’ll ask you to verify. To do that, click on Send Verification Code.

5. Then, enter the Verification Code you receive in your email.

6. Finally, at the bottom of the page, toggle on Jotform Support Access.

After we hear back from you, we’ll have a better idea of what’s going on and how to help.

ご指示に沿って、「Jotform Support Access」をONにしました。
ご確認のほど、よろしくお願いします。
