Unremovable servers in Friends LAN Games

Currently I'm working on load-balancing RakNet, and for this reason I tried to use an nginx server with ip-based consistent hashing. But as a result the server had no ping, but I also tried to connect, and the RakNet Handshake started, but didn't complete, as a result, there is now a Server in the Friends LAN Games, the ping is working, but I'm not able to remove it again.

To reproduce it:

1. Set-up a bedrock server with localhost ip and random port
2. Set-up a nginx server
3. Try to connect via the nginx server => now there is an unremovable server (even after restarting the game / the computer)
