I have a Flint 2 running 4.7.4. When I enable Mullvad VPN client, I lose access to my Nginx Proxy Manager hosts. When the VPN is disabled, everything works as intended. All testing as been done while both hardwired to the router and through Wi-Fi. Any advice is appreciated

What is the network topology from your client access to the NPM host?

Is that NPM host a public cloud server? Access it through IP or domain name?
If it is a domain name, can it be resolved after enabling Mullvad VPN?
