If DeepSeek fails to verify your SSL certificate, here are some detailed steps you can take to troubleshoot and resolve the issue:
1. Verify Certificate Chain and Installation
Ensure that your SSL certificate is properly installed on your server, including all necessary intermediate and root certificates. A missing or incorrectly installed intermediate certificate can cause verification failures. Use online tools like SSL Checker or Digicert to validate your certificate chain[3][9].2. Check Certificate Validity and Expiration
Make sure your SSL certificate is valid and not expired. An expired certificate will fail verification. Check the certificate's start and end dates to ensure it is currently active[8][9].3. Update System Date and Time
Ensure your system's date and time are accurate. An incorrect system clock can cause certificate verification failures because SSL/TLS connections rely on accurate timekeeping[1][8].4. Use a Trusted Certificate Authority (CA)
Ensure that your certificate is issued by a trusted CA. If the root CA is not trusted, you will need to add it to your trusted root CA store[2][8].5. Disable Certificate Verification Temporarily (for Testing Only)
If you're using Python or similar libraries to connect to DeepSeek, you can temporarily disable certificate verification for testing purposes. However, this should not be used in production environments as it compromises security. For example, in Python's `requests` library, you can use `requests.get(url, verify=False)`[1][4].6. Check for Environment Variables Overriding Certificate Settings
Ensure that environment variables like `SSL_CERT_FILE` or `REQUESTS_CA_BUNDLE` are not overriding your system's certificate store. If set, these variables might cause verification issues[1].7. Use Tools to Identify Missing Certificates
If you're still encountering issues, use tools like your browser to inspect the certificate chain and identify any missing certificates. You can then obtain these certificates from the CA and install them on your server[5][9].8. Generate a New Certificate Signing Request (CSR)
If you suspect that your certificate was installed incorrectly, generate a new CSR and reissue the certificate from your provider[9].9. Check Server Configuration
Ensure your server is properly configured to support SSL/TLS protocols and that the HTTPS bindings are correctly set up. This includes checking which port and IP your server is listening on for HTTPS connections[2][8].By following these steps, you should be able to identify and resolve the SSL verification issue with DeepSeek.
