X750 with Verizon prepaid

Hello everyone I love the x750 products. Trying to get it going with Verizon. Everything is working perfectly, only issue I’m having is I cannot access some websites.

With my phone connected it works great I can run speedtests, connect to any website.
But if I connect my computer to the box I cannot access the speedtest.net website, nor facebook. I can only access Google and youtube.

Anyone know what the issue could be? I’ve heard it may have something to do with ipv4 and ipv6 but can’t figure it out.

Thanks!

Do you have openvpn or wireguard on the router?
