Identified Causes

4 原因
#1

断続的なサーバー側エラー

75%

サーバーが一時的な過負荷、データベース接続の問題、またはフォーム処理中の未処理の例外を経験している可能性があり、ユーザーに明示的なエラーが表示されずに送信が失敗する場合があります。

#2

クライアントサイドJavaScriptエラー

60%

フォームの検証または送信を担当するJavaScriptコードには、特定の条件下でのみ現れるバグがあり、フォームが正しく送信または処理されない可能性があります。

#3

ネットワーク接続の問題

40%

ユーザーのブラウザとサーバー間の一時的なネットワークの問題は、特に接続が不安定な場合に、フォーム送信プロセスを中断させる可能性があります。

#4

サードパーティ製サービス依存関係

30%

フォームの送信が外部サービス(例:CAPTCHA、メール送信サービス)に依存している場合、それらの断続的な障害やレート制限が送信の問題を引き起こす可能性があります。

Recommended Solutions

8 ソリューション
💡

Check Server Logs

95%Official
Review server logs for any errors or warnings occurring around the time of reported submission failures.

🤖 AI Analysis

"The user reported recent changes to the website's backend or frontend, and a significant percentage of form submissions are failing. Checking server logs is a crucial first step to identify any backend errors that might be preventing form submissions. This is highly relevant given the recent changes."

💡

Inspect Browser Console

90%Official
Open the browser's developer console and check for any JavaScript errors when attempting to submit the form.

🤖 AI Analysis

"Since the issue affects all browsers and devices, and the problem is with form submission, inspecting the browser console for JavaScript errors is a very relevant step. Frontend JavaScript errors can easily prevent form submissions. This is a direct way to diagnose client-side issues."

💡

Review Form Validation Logic

85%Official
Examine the JavaScript code for form validation to ensure it's robust and handles all edge cases.

🤖 AI Analysis

"The user is unable to submit a contact form, and there are no specific fields identified as triggers. Reviewing the form validation logic is important because faulty validation, even if not tied to specific fields, could be causing submissions to fail universally. This is especially relevant if recent changes were made to the form's logic."

💡

Monitor Server Resources

70%Official
Implement monitoring for CPU, memory, and network usage to identify potential resource bottlenecks.

🤖 AI Analysis

"A 25% failure rate could indicate server resource issues, especially if recent changes have increased load or introduced inefficiencies. Monitoring server resources can help identify if the server is struggling to process form submissions."

💡

Check Third-Party Service Status

60%Official
Verify the status pages or dashboards of any integrated third-party services for reported outages or issues.

🤖 AI Analysis

"Contact forms often integrate with third-party services (e.g., email providers, CRM). If recent changes involved such integrations, checking the status of these services is relevant to rule out external dependencies causing the failure."

💡

Test with Different Networks

50%Official
Attempt to submit the form from various network environments (e.g., Wi-Fi, cellular data) to rule out local network issues.

🤖 AI Analysis

"While the user reported the issue across all browsers/devices, testing with different networks can help isolate if there's a subtle network-related issue that might be contributing to the 25% failure rate, although it's less likely to be the primary cause given the broad impact."

💡

Implement Fallback Mechanisms

40%Official
Consider implementing alternative methods for form submission or data capture if a third-party service becomes unavailable.

🤖 AI Analysis

"This is a mitigation strategy rather than a diagnostic step. While useful if a third-party service is indeed the cause, it's less relevant for initial problem diagnosis compared to identifying the root cause."

💡

Implement Client-Side Retry Mechanism

30%Official
Add a JavaScript mechanism to automatically retry form submissions a few times if the initial attempt fails due to network interruptions.

🤖 AI Analysis

"Implementing a retry mechanism is a workaround for network interruptions. Given that the issue is a consistent 25% failure rate and not described as intermittent network drops, this solution is less likely to address the core problem of why submissions are failing in the first place."
