I have a QNAP model TVS-871U-RP with QTS operating system version 4.3.4.0695 on which the Open VPN service is installed. I distributed the certificate to the various VPN clients and until 12/02/2026 it worked perfectly. Now it tells me that the certificate has expired and the clients can no longer connect. How can I renew the certificate and restore access to the clients? Could you help me? Thanks.
