Freezing of server and errors spamming console

[Verdanix]

I am trying to get a list of servers and I keep getting errors that spam. I am using Geyser, floodgate, Purpur 1.19.4. If I try the join method too, it also throws the errors, but I need to return a value from a method when it is complete

		for (String name : MainPlugin.bungeeApi.getServers().get()) {
		          System.out.println(name);
		}
