🔐 Configuring SSL certificates in the gateway - instructions for end users

To enhance the security of your gateway, you can install an SSL certificate.
This allows for encrypted communication via HTTPS.

🔗 Online Documentation: SSL Support

📄 Certificate Requirements

Please ensure that your SSL certificate meets the following criteria:

• Format: The file must be in PEM format

• Encoding: The certificate must be Base64-encoded

• File extension: The file should end with .pem

• Content: The file must begin and end with the following lines:

  -----BEGIN CERTIFICATE-----
  ...
  -----END CERTIFICATE-----
  

⚠️ Certificates in other formats such as .crt, .cer, or .key may not be accepted.

📂 Uploading and Activating the Certificate

1. Login: Open your gateway’s web interface in a browser
2. Navigation: Go to Configuration > SSL Support
3. Upload certificate: Select your .pem file and upload it
4. Save: Save the settings
5. Restart: Reboot the gateway for the certificate to take effect

✅ Verify Functionality

After restarting:

• Test access: Open the web interface again and check whether it is now accessible via HTTPS

• Check certificate: Click the lock icon in your browser’s address bar to view certificate details

💡 Important Notes

• Certificate expired? Renew it in time to avoid interruptions

• No access anymore? If the web interface is unreachable, temporarily use HTTP or contact support

• Self-signed certificate? In production environments, it is strongly recommended to use a certificate issued by a trusted certificate authority
