high ping while tunneling

I host the mc server and because the damn T-Mobile doesn't support port forwarding, I had to tunnel through minekube connect because it has many useful features, but the ping is high, 130 ping on average, and when loading the world, a few thousand, so when someone approaches someone, they can't do anything for a good few seconds. I used playit GG which has an average ping of 90-100 but you have to buy the pro version to add your own domain. I also tried using a vpn with port forwarding, but the ping was also terribly unstable. Ping on other services is low, so I don't know what the problem is
Internet 600Mb/S, the server has a 12-core xeon, but it is not a problem because the processor is usually loaded by a few, a dozen percent. ram 3200mhz cl20
