DeepSeek Troubleshooting Guide

1. Error Codes

Code	Description	Solution
400 – Invalid Format	Invalid request body format.	Modify the request body using error message hints. Refer to API Docs.
401 – Authentication Failed	Incorrect or missing API key.	Verify API key validity. Create one if missing.
402 – Insufficient Balance	Depleted account funds.	Top up via the Balance Page.
422 – Invalid Parameters	Invalid request parameters.	Adjust parameters using error hints. See API Docs.
429 – Rate Limit Reached	Excessive request frequency.	Slow down requests or use alternative APIs (e.g., OpenAI).

503 – Server Overloaded	High traffic congestion.	Wait 5–10 minutes before retrying.

2. Login Issues

Problem: Unable to sign in.
Solutions:

• Confirm Caps Lock is off and credentials are correct.
• Reset password via Forgot Password (check spam folder for reset emails).
• Clear browser cookies (Ctrl+Shift+Del > “Cookies”).
• For locked accounts, wait 15 minutes or email [email protected].
  Note: For 2FA issues, ensure your authenticator app is time-synced.

3. Page Loading Errors

Problem: Website malfunctions or fails to load.
Solutions:

• Basic Checks:
  “`bash
  # Test connectivity
  ping api.deepseek.com
  traceroute deepseek.com

  - Clear cache (`chrome://settings/clearBrowserData`).  
  - Check server status at [status.deepseek.cn](link).  
- **Advanced:**  
  - For HTTP errors:  
    - **404**: Validate URL accuracy.  
    - **502/503**: Server-side issue – wait 5–10 minutes.  
  - Test in incognito mode (`Ctrl+Shift+N`).  

**4. Browser Compatibility**  
**Supported Browsers:**  
| Browser | Minimum Version |  
|---------|-----------------|  
| Chrome | 89+ |  
| Safari | 14+ |  
| Firefox | 78+ |  
| Edge | 91+ |  
**Solutions:**  
- Update browsers via `chrome://settings/help`.  
- Disable conflicting extensions:  

javascript
// List active extensions
chrome.management.getAll(ext => ext.forEach(e => console.log(e.name, e.enabled)));

**5. API Integration Issues**  
**Problem:** Authentication failures.  
**Solutions:**  
- Ensure correct headers and API key:  

python
import requests
headers = {“Authorization”: “Bearer YOUR_API_KEY”, “Content-Type”: “application/json”}
response = requests.get(“https://api.deepseek.com/v1/endpoint”, headers=headers)

- **Clock skew**: Synchronize system time (max 5-minute deviation).  

**6. File Upload Failures**  
**Problem:** Uploads stuck at 0%.  
**Solutions:**  
- Validate file size (≤2GB) and formats (`.zip`, `.pdf`, `.docx`).  
- Use chunked uploads for large files:  

javascript
const uploader = new ChunkedUploader({ endpoint: ‘/upload’, chunkSize: 5 * 1024 * 1024 });

- Ensure CORS headers:  

http
Access-Control-Allow-Origin: https://deepseek.com
Access-Control-Allow-Methods: POST, PUT

**7. Localization Issues**  
**Problem:** Incorrect language display.  
**Solutions:**  
- Force English: Append `?lang=en` to the URL.  
- Clear cached translations:  

bash
rm -rf ~/.cache/deepseek/i18n

**8. Payment Processing Errors**  
**Problem:** Transactions declined.  
**Solutions:**  
- Confirm card supports international transactions.  
- Match billing address with bank records.  
- Test small amounts first:  

javascript
stripe.confirmPayment({ elements, redirect: ‘if_required’ });
“`
