MySQL error: Can't get hostname from your ip address

Question

I use my remote MySQL database during long time.

But today I suddenly have found that I cannot connect to the database. I have got an error.

Answer 1

I know this question was asked quite some time ago and most people have figured it out by now, but for those who haven't, here was my solution:

Add the port number with the server name in you connection string

connectionstring = "server=server;Port=3306;User Id=UserNAme;password=password;Persist Security Info=True;database=DatabaseName;convert zero datetime=true";
