Hello! Currently Minecraft Java edition makes connections between clients and servers using a protocol called TCP, and Bedrock edition makes connections using a library called Raknet (UDP). The problem with using these solutions is that it is more complex to use optimized software for secure and stable connections, including important AntiDDoS for servers, in addition to the complexity of hosting a server with redundancy. My suggestion is to use the new and universal WebSockets protocol, which would solve many of these problems, besides probably allowing to use Minecraft in restricted networks that only allow HTTP.
