Server Certificate Issue (Log in Post)

I'm trying to install my VPN on my new Netgear router, but keep getting an error that the server certificate needs verification. I have no idea how to solve this issue.  I run my router from a central location and us a Roku 3 connected through a HDMI matrix that is sent to my tv's. I want to be able to run the Roku through the VPN, but it's not technically connected to a computer.  Here is my log
