Hi there! I understand you're encountering constant errors when attempting to order from iHerb's app or web page, and this issue occurs on both Windows and Linux machines. Let's narrow down what might be causing this.

Could you please share more details about the error message you're seeing? For instance:
- Is the error happening during checkout, payment processing, or while loading the page?
- Are you using the iHerb app or the website browser interface on your devices?
- Have you tried clearing your browser cache and cookies or disabling any browser extensions that might interfere?
- Are you encountering the same error on different networks, or just one (e.g., home Wi-Fi vs mobile data)?

Meanwhile, here are some general troubleshooting steps we can try to address common ordering errors on iHerb:

1. Clear your browser cache and cookies to remove any corrupted data that might block scripts or cause errors.
2. Try a different browser or switch to incognito/private mode to see if extensions are causing conflicts.
3. Turn off and on your internet connection or try a different network to rule out connectivity issues.
4. Ensure your shipping address and payment information are correctly formatted without extra spaces or invalid characters.
5. Update the iHerb app to the latest version if you're using it, or verify your browser is up to date.
6. If you use a VPN or proxy, try disabling it temporarily as it can affect ordering functionality.

If these steps don't resolve the problem, it might be related to specific account or server issues. In that case, contacting iHerb Customer Service directly at [email protected] could help get your order processed smoothly1 5.

Let me know the exact nature of the error or any other symptoms you notice, and I’ll guide you from there! Are you satisfied with this initial solution so far?
