When I try to use TcpClient to connect the remote MySQL server, I get following error message:

Host 'xxxxxxxx' is blocked because of many connection error; unblock with 'mysqladmin flush-hosts'

Do you know what is wrong? How can I fix it?

Here is my code

C#

TcpClient socketForServer = new TcpClient("xxxxx", 3306); 
NetworkStream networkStream = socketForServer.GetStream(); 
StreamReader streamReader = new StreamReader(networkStream); 
System.Console.WriteLine(streamReader.ReadLine());

I think your error message is incorrect. I doubt the error message would say "because of many connection". Please correct it with the exact error message.

I think the message is quite correct, just missing the plural form. But I agree the message is a bit weird :)

here is the complete message.
Host 'XXXXXXXXXXXXXXXXXXXXX'is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

TcpClient socketForServer = new TcpClient("xxxxx", 3306);
NetworkStream networkStream = socketForServer.GetStream();
StreamReader streamReader = new StreamReader(networkStream);

System.Console.WriteLine(streamReader.ReadLine());

It simply means that you have reached the connection error limit that is defined in max_connect_errors variable.

Could be a config setting on your database though.

Refer to this article for tweaking your config file.
