(Note: this post refers to Archer VR1210v, even if the forum form allows me only to select VR1200)

I'm trying to set an openvpn on the modem/router, but when I click on "generate" the certificate (as recommended by the setting page), it says that it will take a while, but in reality it takes forever: the progress wheel rotates idefinetly, and the buttos are disabled.. only I can do is usign the other config pages of the modem, and everything works fine, but the openvpn page is no more working... even after a reboot

so, what I can do to stop this process.. and to actually generate a certificate?

thanks
