Is the server exposed to the internet at all? ie, Did you open a port on your firewall to allow inbound connections? If not, then nothing should be exposed to the internet and you should have no problem. Proton is also a vpn not a firewall and really doesn’t offer much protection against attacks. It basically just muddies the water on the origin of your Internet traffic.
