Hello,
I have been using the VPN server application on DS918 + 6.2.3. for a long time. I haven't been able to connect to all devices via VPN since about yesterday. It should be a Synology DDNS certificate issued by R3.
I tried to renew the certificate and create a new one. Unfortunately, the problem still persists. When I tried to start the OpenVPN server on the Asus rt-at56u router, everything worked.
The extract from the log is as follows
Any ideas?
