C # - MySQL - MySql.Data.MySqlClient.MySqlStream.ReadPacket ()

I tried to connect to mysql server using remote connection.

Connection string Server = {IP-}; database = {DB}; UID = {usernname}; PWD = {password};

        try {
            conn.Open();
            sqlCmd = conn.CreateCommand();
            sqlCmd.CommandText = sqlStr;
            reader = sqlCmd.ExecuteReader(); //->LINE 32
            while(reader.Read()) //Add to library
        } catch (Exception ex) { }
        finally {
           //Close connection and reader
        }

      

        
        
        
      

    

and I got this error.
