Hi! I see you're encountering the error message "Interner Fehler..." while using S-ID-Check. To help you best, could you tell me a bit more? For example:

- When exactly does this error appear? (e.g., during login, while verifying ID, after clicking a button)
- Are there any other error codes or messages shown alongside it?
- Have you already tried any fixes so far?

This will help me guide you step-by-step. Generally, "Interner Fehler" means an internal error—something went wrong within the system. Let's start by checking a few basics:

1. Make sure your internet connection is stable.
2. Try refreshing the page or restarting the app.
3. Clear your browser cache and cookies, since you mentioned using WebKit on Windows.
4. Check if your app or browser version is up to date.

If you've done these or the problem persists, there could be an issue on the server side or with your account settings. Let me know what you've tried and any other details, and we can go deeper from there!

The error occurs after I put in the code to start the money transfer. The code is safely correct.

Thanks for the additional info! Since the "Interner Fehler..." happens right after you enter the code to start the money transfer and you’re sure the code is correct, this points toward an internal system issue or possibly a communication problem between your device and the payment server.

Let’s try these steps next:

1. Double-check your internet connection: Though you might be connected, unstable or restricted networks (like public Wi-Fi with firewalls) can cause internal errors during sensitive operations like payments.

2. Restart the browser: Because you’re using a WebKit-based browser on Windows 10, fully close it and then reopen it to clear temporary glitches.

3. Try a different browser: If possible, try the transaction in another browser like Edge or Chrome. This helps rule out browser-specific issues.

4. Check for browser updates: Make sure your browser is fully updated, as outdated versions can cause compatibility problems.

5. Clear browser cache and cookies: Corrupted cached data can interfere with the process. Here's how on your Windows machine using a WebKit browser:

- Go to browser settings.

- Find privacy or data settings.

- Clear cache and cookies for all time.

6. Confirm time and date settings: Incorrect system time/date can cause security-related errors in transactions.

If none of these fixes work, the issue might be on the server side, or something specific with your account or transaction attributes. You could try again later, or if urgent, I recommend contacting S-ID-Check support at [email protected] with your transaction details.

Would you like me to guide you on how to clear the cache step-by-step or try an alternate browser first?
