Re: How to update an expired SSL certificate?
Posted: 21 Oct 2026, 10:49
Please note that the script mentioned is specifically designed for F2-210 and F4-210 models to update *.tnas.link certificates and is not suitable for your F2-420.
For your model, as long as the NAS has a normal internet connection, you only need to restart the TNAS.online service (disable and re-enable it in Control Panel) to renew the certificate.
If restarting the TNAS.online service does not succeed, restarting the entire TNAS device will also trigger and complete the certificate renewal process.
Hope this helps!
