Getting horrible latency on 4th user on network(free account - testing for minecraft network)

Good Day all

I am very new to ZeroTier and would relly like to use this service for my private Minecraft server. However I have run into an issue in the one users latency.

When using the VPN to connect to my personal machine or the serve the user is met with latency up to 10K plus ms delay. and we just tested it to make sure on Open VPN free he’s getting 80ms ping,

Is there something I need to do to allow all users to have the best possible latency?
