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,

So I created a ticket and escalated this to our Developers. Although we don't know exactly when it'll be fixed, we’ll circle back to this thread when we have an update.

Thanks for your patience and understanding, we appreciate it.

承知しました。
ご対応ありがとうございます。
引き続き、よろしくお願いします。
