# Why do I get the “too many requests” (HTTP 429) message – and how do I fix it?

## The “Too Many Requests” (HTTP 429) message appears when our system detects unusually high access activity from your side in a short period of time. This can also happen unintentionally – for example, through programs that automatically request links (Excel, Teams, Outlook, Word), multiple open browser tabs/devices, or shared office IPs.  Fix: Close everything that might be requesting North Data pages, wait at least 30 minutes, then try again.

**What triggers the 429 message?**

Our protection systems limit requests (“rate limiting”) to prevent abuse and automated scraping. Common triggers include:

- **Parallel access**: Multiple browser tabs/windows or multiple devices accessing North Data at the same time.
- **Background calls from programs**: Tools like **Excel, Teams, Outlook, Word** can automatically “ping” embedded or saved links without you clicking them.
- **Shared IP addresses**: In office networks, several people/devices access North Data under the **same public IP** at once.
- **Browser extensions**: Add-ons that **preload/refresh pages** (e.g., Auto-Refresh, Preload tools, SEO crawlers).
- **Automated access**: Scripts/bots are against our Terms and are blocked.
- **Subscription usage on too many devices**: Subscribers can use **max. two devices at the same time**.

Note: Once the block is triggered, it will remain active for about **30 minutes** (“cool-down” period).

**Step-by-step: How to fix the problem**

1. **Close all North Data tabs** – including on **other devices** (PC, laptop, tablet, smartphone).
2. **Check programs** that might be opening links in the background (Excel, Teams, Outlook, Word, etc.) and **remove embedded North Data URLs** or close those files.
3. **Temporarily disable browser extensions** (Auto-Refresh, Preload, Crawler tools).
4. **Log out from other devices** or reduce to **max. two devices**.
5. **Wait 30 minutes** before trying again.
6. If possible, use **Incognito/Private mode** and only **one tab**.

**How to avoid it in the future**

- Don’t keep **multiple tabs/windows** with North Data open.
- Avoid **auto-refreshing add-ons**.
- Remove **embedded North Data links** from Office documents/emails when not in use.
- In team environments, make sure **no more than two devices** use the subscription at the same time.
- For high-volume usage, consider a **Team package**.

**Special case: Payment/Checkout & 429**

If the 429 block is triggered **during payment**, the payment may fail.  
Steps:

1. Follow the fix instructions above.
2. Retry payment after the cool-down period.
3. Make sure your bank’s **3-D Secure/App/TAN** approval is successfully confirmed.

**Contacting Support – what to include**

If the message still appears after following the steps, please send us:

- **Time** of the error and the **exact message text** including **TraceID** (shown in the error)
- **Number/type of devices** (e.g., 1 laptop + 1 smartphone) and whether **others in the same network** were active
- **Programs/files** with embedded North Data links (Excel, Outlook, Teams, Word, etc.)
- **Browser** used and any **extensions** (especially Auto-Refresh/SEO tools)
