io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: /127.0.0.1:11235 when established 2000 connections from netty client program at netty client side

Expected behavior

No Error

Actual behavior

As i am making 2000 concurrent connections(TLS Connections) from java netty client program to netty server which is running on same host. But after 500 or 1000 connections i am getting below error at netty client side,

but when i run the same client program with inserting Thread.sleep(50) i didn’t get above error at client side. So whats the reason or whats wrong in the code?
