I installed the openvpn from:
https://raw.githubusercontent.com/angristan/openvpn-install/master/openvpn-install.sh
after setting it up through this method here:
was getting TLS error, forwarded port 1194 on both my modem and router.
now my openvpn connects successfully but it turns off my entire router's internet.
