duckdns domains no longers works with Wireguard after using with Nginx

[redpixy]

Hi guys,

I am experiencing some issues with my Wireguard endpoint. I was using the "myvpn.duckdns.org" service as the endpoint, which works previously.

Recently I install the docker image of nginx proxy manager, to host my applications using duckdns. - "app1.duckdns.org" and etc.

After setting up it, the "myvpn.duckdns.org" suddenly don't work with Wireguard endpoint. I started getting handshake fails. I tried creating new duckdns subdomains. The handshake error persist as long as it's a duckdns domain.

Is there some config, which needs to be done?
