@0ni0niz3 cool to see that you referred to my past post! I ended up giving up on running my bridge through OpenVPN and I later attempted to run my bridge through Wireguard without luck.
I remember wondering if the third-party VPN/Wireguard server firewall was causing the reachability issue, which would be out of my control.
I will be following any responses to your post - maybe you will find a solution that will inspire me to re-attempt to run my bridge through OpenVPN/wireguard! cheers
