Do you have a piece of sample code to produce this issue? I cannot reproduce it by my test case.

OK, I am trying to reproduce this issue.

Probably this bug has been fixed by this commit: https://github.com/kerryjiang/SuperSocket.ClientEngine/commit/05b893c474a5cf869a75e173e8deb0b129e1fe13

Which version of ClientEngine do you use right now?

v4.0.30319? It doesn't seem like a product version. It might be the .net framework version.

Yes, it is. Could you try the latest version 0.15? Can you use .netstandard library in your project?

Is there a good approach allow me to reproduce it?

Could you try adding this environment variable in the application? Environment.SetEnvironmentVariable("PREFER_DNS_IN_ADVANCE", true);

Did you try this Environment.SetEnvironmentVariable("PREFER_DNS_IN_ADVANCE", true); It is the solution for the error System.NotImplementedException: The method or operation is not implemented
