TLS handshake failure while connecting to OpenVPN server on Nighthawk R7450

I am trying to setup a VPN server on my router so that I can connect to my home internet while traveling. I have enabled the OpenVPN server with the Netgear DDNS and downloaded the configuration files. But when I try to connect to the OpenVPN server using the configuration files on OpenVPN client GUI or android app, it doesnt work. It waits for connection and then there is an error saying TLS negotiation failed.

So far I have tried connecting from a different network, connecting from the same network, using older version 2.4.7 of OpenVPN client GUI. I have tried changing port number to another random port as well as open ports like 443 for TUN and TAP. I have tried using TCP instead of UDP. I have tried completely turning of all firewalls. No matter what I do, it simply wont connect. Some help will be really appreciated.
